It definitely somethng that you have to do at least once, to experience it. We, however enjoy the corny-ness slap stick vaudville style and go almost everytime we head down the WDW. This trip we werent going to go, but the kids really were upset that it wasn't going to be in the plan, so we caved and went once again. They are 9 and 7, girl and boy, and they loved it! We had my brother with us, and he shaves his head, so they picked on him all night and called him Mr. Clean. His son, my nephew is 4.5mo old and one of the female singers came over and planted a big red smooch on his head. I agree with a few others, that yes, if you are not used to loud places or have a few reserved people in your party it probably isnt the place for you. You may want to give the Mickeys Backyard BBQ a try. It has a small band, with a country singer that sings popular country songs, as well as a character appearance by Chip and Dale, Mickey and Minnie and Goofie. The interaction is great and they come out and dance with the kids. There is also a "rope show" and they do conga lines, and line dancing. There is also FREE beer and wine included in your price as well as gratuity, and its a bit cheaper than the Hooptee Doo Review. We did that this last visit which was a first for us and again, the kids loved it.
As far as Whispering Canyon Cafe at Wilderness, another great interactive place, but no characters. The wait staff is hilarious. Just dont ask for ketchup.....if you do, they will grab all the kids at the tables to gather up all the ketchup bottles, and you will have them all at your table. OR.......ask for a "little more soda"......and you will get a mini mason jar the size of a shot glass with a 3ft. straw. Ask for a straw and you are liable to get a box of them dumped in your lap. We went there last time and had a blast.
Ok, so I think I am done for now. Sorry, I tend to ramble on, just ask anyone on here.....LOL whatever you decide you will have a great time!!!!
