To me it makes no sense to have the NBA at Jambo. You can't keep the bubble there when kidani folks can just walk over and if they're bringing back Mara staff, you'll have kidani folks going over for food. I can see them moving Jambo folk over to kidani until the animal kingdom lodge is fully open to cut down on staffing due to the limited number of dvc rooms at jambo.
It wouldn't be any great challenge to place wooden barricades and security at Jambo access points. They'll do that with any resort used to house pro sports teams. Admittedly, Coronado Springs would bring an added level of separation.
It's been implied that NBA may have access to more than one resort. And MLS will need a home too.
