I recently came off of a WDW trip (and I was last at DLR in October) so here are my observations:
Security: I love how quick it is at WDW. Walk right through most of the time unless you have something that sets off the machine.
Food: I loved all of the quick service options at WDW. There are hidden gems in each park. I especially liked the Satu'li Canteen at DAK, ABC Commissary at DHS, Connections Cafe at EPCOT and Colombia Harbour House at MK. I can't say much about other levels of dining but there are more choices at WDW. Epcot, with festivals, also has festival booths in addition to different restaurants in all of the pavilions. I had some great Gelato from the Italy Pavilion at Epcot. For a "snack" the Cheeseburger and Pepperoni Pizza Spring rolls at MK (cart between Main Street and Adventureland) were very good and are absolutely worth standing in line for.
Other guests: I think I prefer the crowds / other guests at DL better. At WDW groups pretty much keep to themselves. Every time I've been to DL it seems that different people talk to one another in line or interact more. DL guests also don't seem to hold up lines and are overall more courteous than MK lines.
Parking: If you show up early in the day you'll get a good spot. If you park hop or show up later in the day you could have a hot hike. Not every lot runs trams all the time. Cast Members don't really check dates on the parking receipts if you already have one.
Overall I'd rank the WDW parks:
1.) MK - It's not
Disneyland but it's -almost- as good. Some of the classic attractions need some TLC
2.) DHS - Incredibly well themed park with a topflight attraction lineup. A decent amount of shows to keep with the whole Hollywood theme.
3.) EPCOT - It has some great attractions and World Showcase is absolutely well themed. It's definitely a foodie's park. A lot of Future World / World Celebration is either closed (see Wonders of Life pavilion) or very dated.
4.) DAK - The attractions that are there are pretty awesome but there just aren't a lot of them. Outside of those attractions it's a Disney Zoo.
Overall domestically it would be:
1.) DL
2.) MK
3.) DHS
4.) DCA
5.) EPCOT
6.) DAK
Magic Kingdom:
- Castle - I love MK's castle. I do like the DL castle walkthrough but MK's is a great centerpiece to that park.
- Mickey's Philharmagic - The quality of the show (as well as the massive screen that spanned the theater) is far superior at the MK versus that minimally modified Muppet's theater at DCA.
- BTMRR - Disneyland's is smooth as silk. I prefer WDW's queue. I do like DL's dynamite scene and additional special effects. The MK version is currently closed right now and appears to be getting a new track.
- Main Street USA - There are some differences. I think I like the location of the ice cream shop better at MK because it's easier to get to from other areas of the park. I also enjoy the food and beverage options in MK's Main Street.
- Tiana's Bayou Adventure - Thematically fits very well at DL, not as well at WDW. I've never been on the DL version, but I think the WDW version is a very good attraction. It's not Splash Mountain but it's very well done.
- Jungle Cruise - Fairly similar to DL. I enjoy the temple scene but on the last 2 occasions I went in the temple the skippers didn't say anything and used this time to grab a drink of water or take a break along the ride. I enjoy the skipper shooting the cap gun at DL and DL has the better queue (I like the multi-levels). If I was to do a ride comparison, I'd give the edge to DL even though there is no temple scene.
- Enchanted Tiki Room - DL has a better pre-show (and I like how the Dole Whip stand is attached to the pre-show). DL also has a working fountain, and its show is slightly longer as a result. Edge to DL here.
- Pirates of the Caribbean - I love the DL version of this so much that MK's is a bit of a disappointment. I like starting out in the Bayou, then meandering down to the battle scene and town, then the extended scenes after the burning jailhouse. If MK has any edge here it is the queue, but DL's version is far superior.
- Country Bear Jamboree - I love the new show.
- Liberty Belle Riverboat - It was hard to hear the narration. It was a nice break in the day but I'm not really going to lose too much sleep once it is closed.
- Haunted Mansion - I like the elevator at DL and DL's placement of the Hatbox Ghost (WDW's doesn't fit the storyline correctly). However, this might be my favorite attraction at the MK. I love the library scene with the "ghost writers," the staircase scene, and the overall pacing of this ride at WDW better. Plus, I think I'm pretty much over Haunted Mansion Holiday, so I like that WDW keeps the regular version year-round. I'll give the edge to MK here.
- Peter Pan's Flight - It's been a while since I've been on DL's version of this. It's a good ride but not worth a wait.
- It's a Small World - Everything about this attraction is better at DL. MK seems to use this as a people eater when crowds are at its peak, and it doesn't get the care or attention that DL's gets.
- The Many Adventures of Winnie the Pooh - The outdoor queue and the setting in Fantasyland at MK is better. I didn't notice many differences in the rides between DL and MK.
- Seven Dwarfs Mine Train - I wouldn't spend anything extra on this ride. It's a good concept and a very enjoyable ride but it's not worth paying extra for or waiting more than 45 minutes for.
- Under the Sea: Journey of the Little Mermaid – Better queue than DCA. Other than that, I believe it was the exact same.
- Dumbo- MK's double dumbo is great for capacity.
- TRON: Lightcycle/Run - Fun ride, a bit short. It seems once you really get into the ride it is over. It, like Seven Dwarf's Mine Train, is not worth its ridiculous wait time.
- Space Mountain - I might be the exception to the rule here, but I absolutely love this ride and could easily spend a day continuously riding it. My kids also love the MK version better. It is not nearly as rough or jerky as the Matterhorn. While the music isn't in the ride vehicle there is music. I think it also has a more intense track layout in comparison to the DL version. The camera flash at the end of the DL version always makes me a little disjointed / nauseous versus the camera flash towards the beginning of the MK version. I'll say I prefer this at MK to the DL version.
- Astro Orbiter - I enjoy its location much better than DL's.
- The People Mover – This is actually a fairly popular ride at WDW and is a great break from walking / standing.
- Buzz Lightyear Space Ranger Spin - This is one of the most disappointing attractions. I think that the DL version needs some TLC but this needs a makeover. Thankfully it appears that it will be getting ones.
- Monsters Inc. Laugh Floor - Fun attraction that everyone in the family can enjoy.
- Railroad - I like everything about DL's better. I believe the stations are better located at DL than at WDW. DL also has the Grand Canyon and Primeval dioramas that don't exist at WDW.
- Entrance / Exit - I understand the idea of the monorail / ferryboat when entering the park. I believe it adds to the entrance experience as it adds excitement as you get closer to the castle. I absolutely hate having to use the monorail / ferryboat after the fireworks with large crowds in order to get virtually anywhere. It is especially challenging with tired children. At DL it's easy to get into a car / get off property / get to the hotel at all times. At the MK it's a bit of a slog. Plus, once you get to the parking lot it's another slog to get to the actual car.
EPCOT:
- Space Ship Earth - This attraction needs to be redone. It's a classic but it has essentially served its purpose.
- Guardians of the Galaxy: Cosmic Rewind - The queue, even with a LL, seems to go on and on to hold room to hold room to preshow, etc. Once you get to the actual ride it's nothing but smiles. This ride deserves every bit of hype it gets.
- Mission: SPACE - I have motion sickness. I did it once about 13 years ago and felt sick for a while afterwards. Never again.
- Journey into Imagination -This was a good ride during the 80s and 90s and Disney ruined it. They need to fix it or reimagine it.
- Living with the Land - Educational attraction. It is in dire need of an update but a great concept.
- The Seas with Nemo and Friend - It's an Omnimover attached to an actual aquarium. I like it better than the subs at Disneyland. The overall concept of the ride is similar.
- Gran Fiesta Tour featuring the Three Caballeros - They seem to have stolen the Disneyland entrance / exit from Pirates (where you enter a boat ride in a dimly lit restaurant) and have it set in Mexico. The ride itself seems to be "finding Donald" set in locations all over Mexico. Kind of silly but cute and air conditioned.
- Frozen Ever After – The queue is kind of fun. The ride itself is also pretty fun, and the ice palace scene / backwards slide is a cool twist. For a reskinned attraction they did a good job with it. It isn't worth more than about a 45-minute wait though.
- Remy's Ratatouille Adventure - This is a cute, well done, fun ride. I did appreciate single rider. Like has been said before it's a lot like MMRRR.
- Soarin' - Same attraction as DL with a worse queue and an EPCOT as opposed to Disneyland scene at the end.
- Journey of Water featuring Moana - Fun interactive exhibit where you can get wet if you want.
Hollywood Studios:
- Mickey & Minnie's Runaway Railway - The setting in Toontown is better than the Chinese Theater. I prefer DL's queue and setting but it's still an underrated, fun ride.
- Muppet-Vision 3-D - It's a classic. I'm sad that it is leaving but is still enjoyable.
- Rise of the Resistance - Same as DL except with single rider. Note that Single Rider skips the transport portion of the preshow.
- Slinky Dog Dash - Another fun WDW attraction that isn't worth more than a 45-minute wait.
- Toy Story Midway Mania - I prefer the location on the Midway at DCA better.
- Rock'n Roller Coaster Featuring Aerosmith - It's a fun, short coaster. The music is neat even if the current theming is a bit dated. Is going to become a Muppets attraction.
- Tower of Terror - I preferred this version to the one at DCA. I like the 5th dimension scene, and it does have a variety of drop sequences. As far as overall smiles though Guardians at DCA is probably the more "fun" attraction.
- SWGE - Overall I preferred DL's version of this land. The attractions and overall layout are very similar.
Animal Kingdom:
- Avatar: Flight of Passage - Probably the best WDW attraction. I loved the smells that are pumped in, the colors and the details. I had a bit of motion sickness, but the details were worth any bit of discomfort.
- Na'vi River Journey - I enjoy the colors and details. It was essentially a boat ride like the Three Caballeros at EPCOT except with much better theming. When I went on it the big animatronic at the end was not functioning and instead there was a screen up of what the animatronic was supposed to be doing. This attraction was a bit of a dissappointment in that respect.
- Kilamanjaro Safaris - This feels like a Jungle Cruise with live animals and on a Jeep. The animals are fun to see and when I went the Lions were posed perfectly.
- Rafiki Train - Fun ride to the Conservation Station. While they had a drawing class a more interesting area was actually the veterinary office where they perform operations on some of the animals.
- Dinosaur - I'm actually a bit disappointed this is closing. I liked the story, and it felt a bit more intense than Indiana Jones. It is VERY dark though.
- Expedition Everest - I didn't really enjoy this attraction. It seems like a more intense version of BTMRR with a backwards section.
