Two huge positives Disney has...
MLS, which will be done in 11 days, worked 100%, after they got through the initial quarantine phase.
NBA, which is still only a few weeks old, is working, after it got through the initial quarantine phase.
So, 2 wildly different sports, 1 indoor and 1 outdoor, have been together at almost the same times, and Disney has gotten them going, and in MLS's case, almost through the whole sporting event. And EVERYONE has learned from early mistakes and new situations.
So, at Disney, no one remakes the wheel. Disney already has a plan for x number of people and x games for transport, practice, food, tv presentation, etc...and they've also employed all the support people ready to do the work...
This might be priceless...
