I am a HUGE WDW fan!! That being said, we are VERY close to DL, and unfortunately spend much more time there than at WDW. That being said, there are some great things about DL.
1) The castle is perfect!!! I like eating in Cinderella's castle, but Sleeping Beauty's castle is by far my favorite!! It is quaint, and more "cobblestonish" where Cinderella's is just plain flashy. Plus, I love that it is pink...it just makes it so storybook-fairytale-like!! I just cannot get enough of that castle.
2) Trees in main st. plaza...I had forgotten how WDW really didn't have any of these. There are LOTS of big trees in DL's plaza, with lights in them that twinkle at night...it is SOO cool!!
3) I don't like seeing tomorrowland right off of main st. at WDW. At DL, it is shielded by the Plaza/Crystal's Palace type restaurant (I don't remember what it is called). I hate seeing tomorrowland when all I feel like I should be seeing is main st, the plaza, and the castle.
4) I LOVE the storybook boats, Alice's ride, and the Indiana Jones ride...I miss them at WDW (although MK makes up for it in so many other ways).
5) The Grand Californian Hotel...enough said!!! I love the fact that DTD is right next to the parks!!! If you go, go eat at The Storyteller's Cafe for lunch or bfast (make PS's). The buffet bfast is amazing, but the "Achiote Chicken Cheddar Melt" is hands down the BEST sandwich I have ever had!!!
6) POC....what a great ride!!! And, if you can get a PS at the Blue Bayou...it is a view of POC that puts the San Angel Inn to shame!!
7) The Aladdin show at CA...the BEST show at any Disney Park!!
8) If you do the Keys to the Kingdom tour, you can get a glimpse into "Club 33"...Walt's baby!!!
Now, the negatives:
It is WAY to small and congested!!! And, it is too "inner-city-ish" for me. Way too many AP holders who come on a regular basis for my tastes. The LA city buses literally bring thousands of people in everyday who act like they "own" the park. People line up for parades VERY early (we always end up waiting at LEAST an hour for a parade spot...sometimes two), and then someone always tries to push in front of us once the parade starts...it never fails!!! Since the park is not full of "vacationers", but is pretty much split between "regulars" and "vacationers", it is just not the same attitude as WDW...people are MUCH less polite. Plus, there are a LOT of teenagers without any adults around...sometimes they can get a little rowdy.
For me, it boils down to this...I feel like I am in a theme park at DL...a place where you go for the day. The world is just "too close" to DL to feel any different. When I go to WDW...I feel like I am in a whole other world!!!
There are good points to DL...but, it is hard to see them the first time you go. After WDW, DL really is an "acquired taste".
