We were there the second week of October. We didn't stay in a cabin as we have our own coach. There was a large group from the camping forum there for a DISmeet. You might want to go to the camping forum and look it up as there are a lot of posts from the day to day and park info from a first hand perspective.
We didn't go to the parks so our stay centered around the fort for the most part.
First, a golf cart. Some people say they don't need them, we feel that we do as it really is the quickest way to get around the Fort, plus it's fun in it's own right to go "looping" just to see the campground. We have rented from Disney in the past but brought our own cart this trip.
There is plenty of cart parking at the settlement near the Hoop D Do Review, Trails End, and in between the trading post and the boat docks. There is also cart parking at the Meadows for the activities there. Cart parking up at the front end right behind the bus stops.
You can get carts from both Disney there at the Fort, and from off site vendors.
When we were there, the boats only ran between Magic Kingdom and back. They did not run to the resorts. The Yellow bus ran regularly to the Wilderness Lodge and back.
Hoop D Do Review was not open. Trails End buffet was not open but there were spaced out tables that could still be used inside for meals. P & J's carry out and Crockett's Tavern, both within the Trail's End building are open for carry out.
Both pools are open and heated. There is a limit to how many people were allowed in due to social distancing.
Gem mining, archery and movies are still running at the Meadows. No campfire or Chip and Dale sing a long though.
Pony rides are available at the new barn, which is located near the settlement bus stop.
Probably have forgotten something but it's a start.
Here's a link to the camping forum where there's a lot more information:
