I totally agree with 2024, I think alot of the attraction has already been built off site in the time they had, and the budget paying for it has probably been slowly on the books since the announcement. So now its strip the mountain, rock work and other building. The quicker it opens and hopefully wows people the sooner people forget about splash mountain (in Disneys eyes), if its down for multiple years then it just adds to the controversy and people missing splash. It took what a year to do Frozen and there wasnt the rush that I think you will see here.
