I think you missed my point on Tunica. Aside from the burgeoning music tourism aspect of the Delta. There's bridge studies that show various options for new bridges over the Mississippi around the Greater Memphis area, one of these options is a crossing from Arkansas to Mississipp iat Tunica. (See the light Purple/Lavender Route)
This bridge would allow for a Marvel Park to be built on the Arkansas Side. I could by designed with passenger rail included. A possible Disney IP park could be built on the Mississippi side where the Riverboat landing is.
This would place Disney Parks a major crossroads of America (I-40, I-55, I-69 along with I-22). It would overcome the Marvel hurdle. the parks in Paris and Tokyo show that colder weather doesn't hamper the parks and we see that most rides are now indoor attractions anyways.
Then there's the airport infrastructure with Memphis International. A 4 runway behemoth that is waiting to be properly utilized since Delta pulled the former Northwest hub out. While it is the second largest cargo airport in the world (sometimes #1) thanks tothe Massive FedEx hub there, their sorts are are at odd times and wouldn't conflict too much with a passenger traffic. It should be noted that Memphis already has over 2 million International Tourist a year with Canada, Uk, Austrailia, Brazil, Japan, Germany and other European countries at the top of the heap.
Again, it's a combination of things that gets me thinking this way. It opens up A new River Cruising market and overcomes Marvel space obsticles in California without canabalizing existing attractions and Florida with competition restrictions. Given the construction lead time the Bridge could be built along with the new boats and parks. Plus you have a ready made airport no farther away than MCO is to WDW nearly ready to go that with enough planning lead time, could hand 10s of millions more in passenger traffic.
Pick it apart if you want, I'm done with it after this post but if I was CEO, I'd be looking at all that wide open flat farmland like Walt did with all that flat swampland and thinking that three different states would fall over themselves to attract such a venture (Arkansas, Mississippi and Tennessee would all greatly benefit from this) Arkansas gave a steel mill a billion bucks, wonder what they'd give for a Disney Park?
