Hey there, Tami! It's great to see you again here at the Disney Parks Moms Panel!
I love Disney's Fort Wilderness Resort & Campground, but we're not big campers in my family. Lucky for us, we can "rough it" in comfort in a well stocked one-bedroom cabin. The cabins make staying in the wilderness even more fun, and are a great base for exploring all of Walt Disney World.
While you're out and about at Fort Wilderness you're bound to get thirsty, so it's easy to make a pit stop to refresh your RapidFill mug. You'll find refill stations at the takeout counter of Trail's End restaurant, and at the snack bar at the Meadow Swimmin' Pool.
And if you'd like to explore some of Walt Disney World's other fabulous resort hotels during your stay, you can refill your mug there, too, as long as it hasn't expired. Just remember that there are no refill stations inside any of the Theme Parks.
I hope this helps quench your thirst for information about the RapidFill mugs, Tami. Wishing your family a magical Walt Disney World vacation!
