Hi Courtney, and welcome to planDisney!
I can only imagine the peace you will experience when you arrive for your stay at
The Campsites at Disney's Fort Wilderness Resort at
Walt Disney World Resort!
I took the liberty of making contact to find the answer to your question related to the cots in the rental tents. Unfortunately, the rental tent cots do not include sheets and pillows, so it might be good to bring your own.
While you are at the campsites,
renting a golf cart is a fun idea because it is an efficient way to get around the campgrounds and explore. Reservations can be made up to one year prior to your visit by calling (407) 824-2742. The golf cart fits 4 individuals and can be picked up at 1:00 PM on the day of your arrival and returned no later than 11:00 AM on the day of your departure.
Please let us know if you have additional questions; we are here to help.
Have a magical adventure!
Raquel
