I am not a basketball fan. Not even a tiny bit.
I think it's FANTASTIC that Disney is doing this. It is pouring tons of money into the company at a time when they are struggling more than ever before in their history. It is filling a couple of hotels, getting the Wide World of Sports complex running, and keeping likely hundreds of cast members employed. It's also obviously perfect synergy since they also own ESPN so it's feeding that and keeping those people employed as well.
I really don't see how anyone can find fault with this arrangement unless they got closed out of the hotel they wanted to stay at because it's now being used exclusively by the NBA.
There is an argument to be made, I suppose, about whether or not there should be sports at this time in the midst of a pandemic, but I think the NBA and Disney are doing it as safely as they can. It does bother me that these people are getting COVID tests regularly so they can play a game and I have to jump through hoops to get patients tested, but other than that, I've got no issue at all with what they're doing.
