It's not as easy to get mail at a resort as it is to send it--in January, my Grandma sent us something Express Mail on property, and it was in Orlando from WV the next day, but we had to go to the Lake Buena Vista Post Office to pick it up--no signature required or anything, but we still had to go in person. If you're just sending regular old mail, you're better off to call your actual resort and get the actual address, and inquire as to the process. We've been successful, and it can be done, just give yourself a little extra time.
