^I agree. Disneyland has always been more of a locals park so they need to add different overlays and update rides more often. The Florida parks are where people go for their 'trip of a lifetime', and they want the original versions of rides. I don't understand putting a Guardians overlay on Tower, but I'm sure Disney will figure out a way to make it work. I mean, as long as it gets rid of that terrible 'hallway to get on an elevator after elevator doors' I'm good!
That being said, any of the Towers are welcome to convert to a Shiriki overlay anytime they want!
