Our family's resort restaurant favorites (one dining credit choices) are:
1. Ohana at the Polynesian (really fun with kids; there is entertainment and the meal is served family style, all-you-can-eat. If you time it right, you could be there to watch Wishes from the restaurant or beach)
2. Boma at the AKL (one of our all-time favorites. This is a buffet meal with a lot of choices--we are not usually adventersome eaters, but everything was delicious! Spend some time before or after your meal exploring this great resort.)
3. The Grand Floridian Cafe (Again, terrific food plus beautiful atmosphere. You can spend some time exploring this resort, too. There is live music in the main lobby, plus the grounds are magnificent. You could even loop the monorail for an after-dinner joy ride!).
4. Whispering Canyon Cafe at WL (very noisy, but fun for the whole family. Food is pretty good. This restaurant is just off the main lobby, which has a lot of wonderful features to explore while you wait).
Good luck!!
