You just have to call and tell them your dates, and they'll tell you what resorts are available and what the rates are. There are only a certain number of rooms available at any time, so call as soon as you know your dates and it would probably be a good idea to have a few resorts in mind so you can ask about what you most likely want. When I called, I waned a monorail resort and got quotes on Poly, Contemporary and GF and chose the GF offer. Good luck and have fun!
