Well you don't really need Disney world for it to work. You just need players to not return to their homes, have no close contacts with friends or relatives and limit travel and you easily create a safe bubble in any holiday resort.
The Prem has 12 cases with players returning from holiday, Serie A already has 8 new active cases in the last two days. It just makes very little sense for other sports like the NBA or F1 to take such measures and football isn't doing anything (and even plan on playing with audience in Italy)
