Disney's Fort Wilderness Resort
It's time for a Hoe-down! Host a fun, relaxed "welcome party" at Disney's Fort Wilderness cookout pavilion. This pavilion can host groups sized from 25 people to 250 people and allows you and your guests the perfect setting to gather together the day before the wedding.
