We did this once and it was terrific! We loved the character interaction, dancing with everyone was a real treat. We aren't country music fans but we had a great time. Food was pretty good. Usual bbq fare. I liked that you could get beer & wine too, nothing fancy, but a nice touch.
I would highly recommend doing this at least once. We were there in the fall so the heat wasn't an issue, as for bugs, I don't remember that being an issue either.
