We've done the BBQ a couple of times and really enjoyed it! The food is buffet style, they have lemonade, wine, beer, and cans of soda.
I thought the character interaction was well worth it. It's not too crowded (or at least when we were there), so the kids got to spend a lot of time with Minnie and Mickey, Goofy, Chip and Dale. The roping show was fun and they teach line dancing as well.
Have fun!
