As they sometimes say in the wilderness
"Howdy Lana!"
Thank you for visiting the Disney Parks Moms Panel with such a great question and I must say that it's my absolute pleasure to assist with your dear families upcoming plans to visit the magic of Walt Disney World Resort.
As you mention in your question you're considering bringing an RV and a tent to stay in I wonder if perhaps you're enquiring about
Disney's Fort Wilderness Resort & Campground rather than
Disney's Wilderness Lodge which only accommodates Guests within Resort hotel rooms.
Disney's Fort Wilderness Resort is one of my families favourite spots on Disney property! We absolutely adore the peacefulness of this delightfully rustic Resort and have enjoyed many stays within one of the
home-away-from-home-sweet-home Cabins. I just know your whole family group is going to have a super pixie dusted time
glamping and not camping within your RV & tent combo and as a parent to a family which now totals in 7 - I can completely relate to needing to know about the provision of additional bathroom space! Which is why I'm truly happy to share that
yes indeed you sure will find adequate facilities within the conveniently placed Comfort Stations at Disney's Fort Wilderness Resort & Campground. Each air conditioned Comfort Station benefits from not only private showers and restrooms but also
Laundry Facilities, pay telephones, a phone to the
Front Desk Services and a handy ice machine.
Have a great Disney day.
