Disneyworld unfortunately will probably have to restrict access to a lot of people. That's probably a sure bet. So how do you choose? Yes one option is to just make it an open chance, just show up at the gate. First come, first served, but they have ALWAYS wanted folks to eat, play and sleep in their fiefdom. One way to get that is to link admittance to staying onsite. And I think they should. If someone is forking over the dough to stay say at a MK resort, they should get guaranteed admission.
But I always get flamed because I don't ever think anyone is entitled to a Disney vacation, no one has some God given "right" to get in.
The problem is they have a hot commodity but limited space. In all scenarios someone is going to be left out. If you're a business you definitely don't want it to be your high spending folks
