But we are getting off-topic.
I would still prefer Indy in DHS, but putting it in Adventureland would be a nice addition, assuming they have the space.
I personally would prefer to see IJA in Adventureland over anywhere else, for super controversial reasons that I bet very few people here would agree with:
My reasoning is that Magic Kingdom, for better or for worse, is viewed by the general public as WDW's "main park." As a result, many people go there first, a significant chunk of people go
only to that park (to them, it
is WDW), and the attractions/experiences there are probably what people remember most often as having been the "Disney" attractions/experiences. Basically, it represents WDW. Therefore, it should represent the absolute best of what Disney has to offer. But strangely, the absolute most impressive experiences at WDW are (arguably!) in the other parks - World Showcase, Pandora, Tower of Terror... (I know this is semi-subjective, Splash and Mansion are wonderful, etc., but you see what I mean). And with Tron being the first real E-ticket at the park since 1992, it needs more in order to stay ahead of Uni's lineup. IJA is a fantastic, tried-and-true attraction that's also very high capacity and can be made to fit well in MK's Adventureland. Plus, an updated/expanded version with additional show scenes and effects would make it even more of a home run.
That said, an Indy land (or mini-land) with a version of IJA and a version of Raging Spirits would be an excellent addition to DHS - especially because it could be a lush jungle with waterfalls and the like, which is a type of environment that DHS lacks. If that were the case, I just hope that at least one or two high-quality mega e-tickets are in the works for MK, to make sure it remans worthy of being "WDW" to so many people...
