We went twice last year.
H and I were on a solo trip in January, and had never been to Hoop de Doo before. Friends raved about it, so we decided to give it a shot. He had a blast - the show was funny, the food was really good, and it was a fun night. When we returned in November, we had our DD(3), MIL and FIL with us, and thought they might enjoy it as well. It was mostly a different cast, who were not as talented or funny, and the food just wasn't up to par with what we'd had the previous visit. All in all, we enjoyed ourselves, but it wasn't the rousing success from the trip before. H and I are going to WDW alone again in Sept., and we will skip Hoop de Doo this time. I would maybe consider going again (if available) in a few years, when the kids are older.
