I agree. Not houses but an off property hotel is possible. There are so many hotels and all they need is some place they could lock down. I was thinking if they don’t bring all 30 teams the 4 Seasons may be perfect. They have around 800 rooms and are pretty isolated from fans attempting to get in Plus higher end, with these star players being spoiled the All Stars would be a tough sell. The other option is to split into multiple boutique size hotels (2 or 3). If they stay on property CSR looks like the perfect option. They have 2,000+ rooms plus the convention space so they could easily fit the 35 people from each team even if all 30 teams come. The convention space could be used for team meetings, media setups and possibly even temporary practice courts.
I think the reason people are worried about an impact is there were some who suspect Disney will keep all of WDW shut down until the NBA leaves (Sometime in Sept). I don’t see that as necessary or likely. The sports complex is isolated from the parks and resorts and easy to lock down. CSR could be easily locked down. The only issue might be players wanting to go to the parks on their off days
