Thank you, all!
What three FPs would you recommend for MK, Epcot, and AK?
Since I'm a Disneyland vet, what can I skip at MK?
What are the can't miss attractions at MK for a DL vet?
As someone who grew up very close to Disneyland for many years of my life and has been going to WDW several times over the past couple years, this is what I recommend:
Fastpasses:
MK: Big Thunder Railroad, Seven Dwarfs Mine Train, 3rd FP: (Peter Pan, Splash Mountain, Space Mountain). You won't go wrong with any of these as a 3rd FP.
EPCOT: Test Track (rope drop Soarin or Frozen Ever After), Spaceship Earth, Mission Space.
AK: Flight of Passage (even though this has been very difficult to get unless you are doing a 4+ day trip. Things could change by the time you go), Expedition Everest, Kilimanjaro Safaris or Kali River Rapids for a 3rd FP. (If you can't get a FoP FP, then get the fastpasses that I put an "or" between. You should then rope drop FoP or wait until the evening before closing to get in line. Pandora is amazing so really try to get on the attractions there!)
Disneyland vet skipping at MK:
- Little Mermaid: This is the only attraction in the Magic Kingdom that is the EXACT same as the Disneyland (DCA) version (not including rides like Dumbo). It has also been a while since i have done Buzz Lightyear at MK, so i can't remember if that is the exact same. I know the ride vehicles aren't the same.
- If you don't want to be disappointed, don't go on Pirates of the Caribbean. The Disneyland version is 100x better! It is still worth a ride though if you like Pirates of the Caribbean. I usually always go on it.
- Definitely skip the Tomorrowland Speedway.
What are the can't miss attractions at MK for a DL vet:
- Jungle Cruise, Haunted Mansion, Peter Pan, It's A Small World (keep in mind this is all inside

), Winnie the Pooh, etc. are all still worth going on because they have different aspects to them.
- If you want to remember the past, Country Bear Jamboree and Carousel of Progress are at the MK.
- Festival of Fantasy Parade
- Happily Ever After Fireworks Show
- PeopleMover!!! I wish Disneyland still had the PeopleMover!
- I really enjoy Mickey's Philharmagic which is a 3D Movie Show.
- Hall of Presidents (if it is open when you go).
I would really choose your favorite attractions at Disneyland and see how they compare to the version at WDW.
You will have a great time regardless of what you decide to do. I hope you have a great trip and enjoy the cruise!
