I've done the Backyard BBQ if that's what you mean? which is held close to FW/WL if that's what you mean? A kind of dinner show, bit of Singing, Line Dancing, where everyone can just get up and dance...that sort of thing, all you can eat and yes, drink too. Good fun, though a little pricey because beer's included, but the food is tasty!
I've not done the Hoop-de-doo one though. Same sort of thing but the entertainment it better. A proper show performed for you I think though, as opposed to the informal entertainment of the Backyard BBQ.
As for worth doing....well, I'm glad I did the BBQ, but I didn't think is was so good to go back again, so make of that what you will!
