I have a good "Cure":
Even though I hate the new Tiki Room, several "types" of guests do. (Especially the kids due to the line 'hakuna tostata', oh brother)...
We can choose as an audience which version of the Tiki Room we'd like to see. Two buttons would be placed, one signaling the old show and one the new show. So, all that needs to be done is create a small revolving piece under the "grass". The fountain and Uh-Oa will switch when the show starts based on what the previous show was.
If it were my choice, I'd just update the old bird animatronics, sound system, add new jokes, and maybe a couple more scenes to the original (that means cutting down on the verses of some songs)...just "hyping it up" a little without destroying the quality of Walt's original classic...
Anyway, they've gotta get Iago (as a host) out of there or I'll never be able to enjoy the ole bird show again... :-[
