Marvel potentially coming to WDW? Cool.
Disney finally deciding to use the popular and interesting IP of GotG in the parks? Like it.
Fast-tracking GotG to be added to DHS to spice up that park prior to Star Wars? Makes sense.
Replacing ToT??!?!?!? Huh? What are the decision makers smoking that makes this even seem like an idea that could be discussed, let along approved?
Looking over WDW1974's description of the development is interesting. We know where the Marvel land is going in DCA (next to their ToT). ToT there is kinda tucked away and it would be easy and even make sense potentially to convert it to GotG and have it be mart of a larger Marvel land there. I'm not going to say that I love the idea or anything, but it works and there's a certain logic. It can be broken off from Hollywood Land kinda easily.
But it doesn't make any sense in WDW for so many reasons. It doesn't fit the theme of Sunset Blvd and would be out of place. DHS can't lose arguably their biggest headliner for the refurb with so much already shut down in the park. And DHS desperately needs additional attractions, not replacements (and has space for more stuff if they were willing to put the money in). Why would you waste money re-skinning an already awesome attractions when the park could much better benefit from a bunch of other rides instead?
And isn't DCA's ToT very different in structure to DHS's? If so, how easy is it to "clone" between the two anyway?
Here's my idea that makes this more plausible and sensible: OK, re-theme ToT in California, but you leave it in Florida. You don't want a second drop tower in DHS, so you use one of the expansion pads (or re-place something like Laugh Floor) in Tomorrowland to add this new GotG drop there. Since that ride would be the same mechanics as the DCA ride, it would be easier to clone (though you obviously spend more as new build).
All this said, I'd rather they build a novel new GotG ride in DHS. The park needs all the help it can get.
