I actually went to this tournament in 2018 for my sister's game. If you've ever been to a volleyball tournament, they pack in courts and people like crazy, so, yeah social distancing ain't happening unless they heavily modify how they lay out courts.
Ironically, attending this tournament was how I indirectly found the forums. Our family hadn't been to Orlando in a decade, so we decided it would be a great opportunity to visit WDW again. We only did a full day at Epcot and a half day at Animal Kingdom, but I think my family and I were a little disappointed (I mean, AK has like six rides and Disneyland has 30, so...). It actually led me to search for Universal information to see if we could sneak an IOA trip in, which led me to these forums.
Funny how the world works.
