I would do Crystal Palace, unless you dislike buffets. (I love them.)
There are LOTS of choices at the buffet. I made a meal out of the varied salads, veggies, and desserts alone; my DH had shrimp, salads, and some hot entrees; my dd probably had chicken nuggets and dessert. (If you have any people with special menu needs--e.g., picky eaters, vegetarians--you are probably better off here.) The restaurant is very pretty, and the character interaction fun. They have a parade about every 30 minutes where kids can march along. Okay, okay, I marched along too! (My dd wanted to, but wanted me to come.) You only live once!
I do like Liberty Tree Tavern, but my understanding is that it is sponsored by Stouffer's, and that the dinner is in essence the Stouffer's thanksgiving dinner. I have plenty of Stouffer's Lean Cuisine in my freezer, so this is not meant as a put down of that brand at all, but when I'm on vacation, I'd like something a little different. The LUNCH at LTT offers a somewhat more varied menu, so I would recommend that if you want to try to the restaurant. I had a very nice salad there a couple years back...maybe The Colony Salad?
By the way, I LIKE the way they call each family individually at LTT! IIRC, they yell your name and state, e.g., "The Anderson Family from Connecticut!" Maybe this makes me a big cornball, but I like little touches that fit the theme like that. (I wonder what they do if you are from England, though.)
