Hello! I will get you started. Buses run within the campground to all the camping loops. You can get off at the main FW gate, where you can catch buses to all other WDW areas. You can also catch a boat to the MK and MK-area resorts. The campground is large and some families rent the golf carts by the week. This way you can zip around to the pools, camp stores ("trading posts") etc. I believe you cna get info on these things at the Ft. Wilderness section of WDWIG (Deb Wills' WDW site). The folks at the camping board here can answer a lot of questions too.
The cabins have full kitchens. You can cook "in" with supplies form the Trading Post. They have basics -- bread, milk, eggs, sandwich fixings, soda, some frozen things, ice cream, coffee, and great FW souvenirs. Sometimes they offer the refillable drink mugs. Lots of folks were using the golf carts to visit the Trading Posts when I was there last Spring.
Meals come from one place -- Trail's End. This is a rustic-type restaurant that offers breakfast, lunch and dinner. Each meal is buffet-style and reasonable. There is also a place here to order pizza for eat-in or carry-out. You can also do the Hoop-dee-doo but you need serious reservations! Menus are available at WDWIG.
There is a campfire many nights. They show a movie outside, have a campfire and sell hotdogs and s'mores. A hayride is also offered. We didn't do this but it went by us and it looked FUN! There is also a petting zoo and you can rent bikes and (I believe) fishing poles and canoes at the main trading post. There are rental boats at the marina.
This is a wonderful, relaxed, friendly place. My kids LOVED it. I hope you all will too.
