It would be best to call Dreams Unlimited, they list Fort Wilderness on their website for reservations. Also http://fortwildernessrvrentals.com/faq/ says they will work you to reserve a camp site along with one of their trailers. Its actually an easy process to make the reservations on your own, it takes a bit of leg work. First figure your dates and see if a campsite is available, then check some of the RV rental companies to see if a RV is available, once your have a match on both ends make your reservations.
Ok thanks. I do have everything pretty much figured out. Just thought it might be nice to have one point of contact. I've listened to a lot of the Dis Unplugged and I think I'd like to work with them if possible.
