50"s Prime Time in Hollywood Studios can be a lot of fun, always depending on the server (You could mention to the person who you check in with that you want your sons to get the full experience. Besides being decorated like a 50's kitchen, the servers will admonish you about elbows on the table, not eating your veggies, not finishing everything on your plate, etc. The are looking to be like Mom or Dad and how they would talk to the people at the table that "disobey" the rules. I have had stomach surgery and cannot finish all the food, and that starts them going until I tell them why. It an be a great deal of fun VERY noisy. Other suggestion is the Tusker House. It is a character meal, but we go for the food. If you book the last seating for breakfast then while you are there you will get breakfast and lunch food, some very different, some pretty normal food wise. Germany in Epcot a lot of fun, it is an inside beer garden with an ompa band. Enjoy yourselves.
