Attended the Grovesnor one in Dec. 2002. They had a nice all you can eat buffet going on that had prime rib (not thick pieces but it was good). As you begin to eat some of the characters come around and greet you to get you involved later on. The show itself takes place in the dining room as your eating (quite literally at the table next to you). It was corny but we did have fun and thought it wasn't a bad price (got it off of Ticketmainia for $32 then). I like the Grovesnor Mystery show better than the Hoop Dee Doo. Not too many will agree with me, guess I have a different perspective. The show itself wasn't overly crowded but there were a few people there that had seen the show at least twice. If you ask would I go back to see it again, I would respond probably in 6 to 7 years. There are plenty of shows to see inbetween but I can guarantee that Hoop Dee Don't will not be one of them.
Have fun and enjoy.
