We have done both, and my family would all agree if we were going to repeat one, it would be Hoop Dee Doo. We thought it was a lot of fun, we actually liked the food (the beer and Sangria didn't hurt either), and it was more of an "Event". We try to plan for one event each night of our trip (could be Fantasmic, Illuminations, Wishes, etc.). HDDR was our event for our Animal Kingdom night, and it fit the bill perfectly. YOu are actually getting a meal at the same time, while Boma is JUST a meal. AND I will buck the trend and say we really didn't like the food at Boma. While it was a pretty neat setting and we enjoyed going outside to see the animals, we could have accomplished the same thing by just visiting the hotel. Food-wise, it wasn't for us.
