I went to this in 1998 and was very disappointed. The food was good but mostly meat - I suppose that's what you'd expect from a BBQ.
There was beer, coke or other soda (I don't remember which).
The entertainment was a country band and line dancing. There were a few games outside for the kids - knocking things over with balls type, fairly rustic. I think there was some other entertainment but it wasn't too memorable.
The characters were the best part, Mickey, Minnie, Goofy, Chip and Dale dressed up in Wild West outfits. Minnie danced with the children and all waited round for photos.
We were very bored and went to get the bus back to the car park and had to wait ages.
The evening was made worse by the fact we had booked via Virgin and all of the guests were British giving it more of a Butlins feel than Disney.
If there is a crowd of you who enjoy line dancing you'd probably have a good time but my family didn't really enjoy it.
