There is a storage lot area. It is in front by the settlement check in area. It is "first come" parking area, but I have never seen it full.
You cannot store your RV at Ft. Wilderness. You can get rates for up to 30 days at the campsites. It would be cost prohibitive though. You'd be better off going through a local storage company for your time on the cruise.
They have parking,for large vehicles there isn't any weekly rates at fort wilderness.
