I'd be surprised that, if this were even a possibility, they would use the Pop-DAAR complex. Sure it's the closest, but the perceived luxury/living standard would be incredibly low, especially considering most people would have to be in Pop's Rooms as opposed to AoA's nice rooms. Plus, I have a "feeling" that, if/when WDW would start to come back online, resorts with designated, non-bus transportation would be prioritized.
Between this priority and a lack of convention business, I feel like the perfect answer would be Coronado. It's a huge resort that is basically its own mini city with multiple restaurants at a variety of levels. Plus, it is relatively close to ESPN still, and the convention facilities could be used for extra practice.
