We have stayed in a Ft.W cabin for two summers in a row. It is DH & I and 5 children 10-2 yrs old. We love the cabin feeling and having a full kitchen. There is plenty of room and although there is only one bathroom it is pretty big. Nothing like throwing a waffle in the toaster for the kiddies while mommy takes a shower in the morning.
The transportation is really good. There are internal buses that take you to either the marina(to catch a boat to MK) or to the outpost to catch another bus to the other parks. We usually take the boat to MK, but drive to each of the other parks.
You park your car right at your cabin door. Taking the van to the parks is easier for us because we have 2 little ones in strollers. Coming back for the waterparks is easier too, than riding a bus in a wet bathing suit.
There is a campfire/sing-along each evening that is lots of fun with Chip & Dale, as well as an outdoor movie. We love the Ft.W cabins.
