1. Florida greenlit the WWE to hold their events there a few months ago. So they figured they wouldn't have to jump through a lot of hoops to get the greenlight.

2. Disneyworld, on paper, is a decent place to think that you could create "a bubble." It already has most of the infrastructure to maintain a population of hundreds of people cut off from the rest of the state. Due to baseball spring training, both Florida and Arizona in general have this pre-existing infrastructure.

3. Warm weather state that most of the players actually like going to.

Of course, the state government in Florida is fun by a bunch of moronic shitheads who opened everything too quickly in order to make the Dipshit in charge happy, so here we sit.
