If you are staying at WL, take the ferry to Ft. Wilderness.
The Meadowlands Recreation area is only 1/2 mile walk or you can take the bus. Gift shop and snack bar which is open seasonally. The Meadowlands Recreation area is where you will find the Chip-n-Dale sing-along and movie. There is also an arcade and the bike barn ... you can rent golf carts, bikes, fishing poles, canoes, paddleboats (for use in the canals). There is a volleyball court, shuffleboard, tennis court, playground as well as the pool. The pool is off-limits unless you are staying at FW ... not sure about the other things like the tennis courts, etc.
At Pioneer Hall (near the Marina) you will find a gift shop, porch w/ rocking chairs, Crockett's Tavern (pizza/drinks), Trail's End Buffet, Hoop-de-do-Review, wagon rides, carriage rides. This was also where the petting zoo was located ... not sure what is still there. They also stable the horses from the MK there as well. Believe there is still a guest relations window where you can ask questions/buy tickets.
At the marina you can rent water sprites and pontoon boats for use on Bay Lake/Seven Seas Lagoon. You can also sign up for guided fishing trips.
At the Outpost (front of FW ... just a bus ride from the marina/Pioneer Hall) you can go horseback riding. They also have a kennel for pets.
There is a lovely walking trail from WL to FW as well.
