The remains of the Tropical Serenade aka The Enchanted Tiki Room (aka a Top 10 Fanboi nostalgia lovefest) looks like it is about to fly the coop for good.
According to multiple sources, the attraction, which saw a reprieve a few years ago when it went back to a shortened version of the original 1971 show from the poorly received Under New Management update following a fire that damaged the facility, is on the chopping block and very, very likely to leave.
At this point, I will only call this a rumor (but the gondola system is a rumor and happening, the Rat ride at EPCOT is only a rumor and is happening, the Speedway removal is a rumor and is happening, the new DVC at CBR is a rumor and is happening and the Star Wars themed BOUTIQUE resort experience is a rumor and is most definitely happening).
As to what will replace it, that is unclear at present and one source even suggests it could remain with a new Stitch overlay reusing the pricey AA just like TDL has, but I don't see that.
And with other plans for Adventureland percolating, and Disney having no care for its past beyond shilling merchandise and D23 events and the like, I would expect Jose and Fritz and Company to fly away for good in the near future.
