My family is going to Disney soon but we are having trouble deciding what resturaunts to make reservations for. The oldest person in the group is 60 and the youngest is 12.
Pretty much any place will be able to handle a group and is family friendly - just look at what type of food you think everyone will enjoy and go from there.
Some of our favorites from our December trip (party of 12, ages from 1 to 65) Whispering Canyon Cafe, 50s Prime time, Crystal Palace and Chefs de France.
For a family of all ages, I would suggest the Hoop De Doo Revue. It is a dinner show and entertaining for young and old alike. Good comfort food too. Fried chicken, BBQ ribs, strawberry shortcake. It is two table service credits for each person but a good deal IMO. (Also all the beer and/or shangria you can drink along with bus service back to all Disney resorts). It is located at the Fort Wilderness Campground.
