We did the DDP with my 3 children last September (05). They were 8, 4 and 6 mos at the time. (This was before all the child menu changes!) Here is where we ate our sit downs-
lunch- 50s Prime Time. Kids were entertained by the TVs and ruckus going on all about. They liked the food too- a good sit down for kids.
lunch- Sci Fi drive in. My boys really liked it- liked the cars, liked the movies, liked their food. My 6 month old hated it, but that's a different story. She was tired. I also recommend for kids.
dinner- Cape May- good points were that it was a buffet, the kids had lots of choices (although the pizza was so gooey, my son couldn't grab a slice), and they could immediately eat. The down side is, I have discovered that it is HARD to do a buffet with kids, when they are not old enough to get their own food. I rarely felt like I was enjoying my meal, cause someone always needed something! We do not have any buffets planned for our upcoming trip for exactly this reason.
dinner- Marrakesh- the kids were a little bored here. The kid food selections were fine, and they liked the bread. But it was kind of a long meal, and it was so LOUD and overwhelming at times (the music is INTENSE- esp cause we were right by it). My parents thought the food was so great, but I did not. I would not recommend this one....pretty tile work though!
dinner- Whispering Canyon- this is our favorite with the kids. They love the pony races, they love the waiters yelling and making jokes, and they LOVE the food! We go here every time and never have had a bad experience. I like it cause it's all you care to eat, but there is no buffet to go up and down to- they bring it to you! Everyone is happy.
dinner- Cinderella's Royal Table (when it was sitll 1 credit). OK, my kids LOVED eating in the castle, and they still talk about it. But we had to wait a long, LONG time to get seated- I would say a good 30-40 minutes past our ADR time. That was frustrating to sit in that waiting area, jam packed full of people, when we were hungry. The food was tasty, and like I said, the kids loved eating in the castle- I'm glad we did it.
I also think that Teppanyaki would be a fun choice- we haven't been there with our kids, but they enjoy going to Benihana with us here at home. And although I just dissed buffets, I have to say some of the best food I had on my last trip (which was sans kids) was at Crystal Palace- if you can handle the buffets, go here!
