That is a tough situation. As you know the wait within Ft. Wilderness can even longer than at other resorts because you have to take a set of internal buses (that run within FW only) in order to get to the bus system that takes you to the parks.
It seems like many people solve this by renting a golf cart (which is not only practical but would be fun!) but I don't think that 6 people could fit on a golf cart. I don't suppose at least 2 of those 6 are little ones that could fit on laps could they? The golf carts have 2 bench seats (one facing front, the other facing back). There may be rules about how many can go on a golf cart. The Camping Discussion Boards would be very helpful in that regard.
Otherwise..... here's hoping for some pixie dust on a fantastic car deal!
