Way back, on our first trip, we did Mickey's Luau (it has since been discontinued) and it had Mickey, Minnie, Goofy, and a few other characters in a show along with the fire dancer, etc. My then 4 yr old son fell asleep before we had all our food served and he had even taken a nap earlier that day. Personally, once we did the luau, there is no reason for us ever to go back. Food was not that good (it may have changed since then), seating was very awkward and it was just a waste of time.
Hoop de Doo is lots of fun, but I found the food not that good. Unless they have changed the food since then, the "strawberry shortcake" was terrible, the fried chicken was old and the rest was not that good.
Mickey's Barbeque was fun, food was not as bad as the other two and lots of little kids enjoyed the dancing and music. This one is outdoors in a covered picnic area. However, we left after a short time because we were bored, as was our son.
