Flame me, but I actually enjoy WDW's Tiki Room. For those of us who wouldn't die for the original version, the new show is actually a lot of fun. The AA Tiki Goddess is spectacular, the songs are catchy, the Iago and Zazu banter funny, and the show fresh. I'm not saying they should change Disneyland's (they shouldn't) but I really didn't find much to dislike about WDW's version.
I especially like the end, where if you hang around inside long enough, you can hear Iago telling Zazu "I'm kinda tired...I'm gonna fly over to the Hall of Presidents for a nap." Priceless.
