Yeah, this happened a few days ago for reasons that remain a mystery.
People speculate that it could be due to the possible pending NBA deal which would bring the NBA playoffs to WDW/ESPN Wide World of Sports in late July. Coronado Springs has been the rumored “bubble” resort that would be used (it has been blocked off for reservations for awhile now) but perhaps CR could now be in play now as well. All speculation at the moment, of course.
Relative to the other resorts, CR does have a number of suites (very large ones at that) that could be used for housing or various functions. CR is also small/compact and easy to secure if needed. It seems in the realm of possibility that it could be in play for some reason.
If I put my marketing hat on, there’s a small part of me that says they should use the CR convention center as one of the courts - the optics of aerial shots of basketball being played inside one of the most iconic hotels with arguably the most iconic theme park in the background would be pretty compelling / good advertising for WDW, in my opinion.
Again, all speculation on my part. I guess we’ll know in due time.
