We stay at the Cabins once a year when we do our whole family trip. The cabins are very comfortable. There is a large bed and bunk beds in the main room and a murphy bed in the living room. All the cabins come with a fully equipped kitchen, including all dishes toaster and coffee maker, and have a grill right outside the door. You also get daily maid service. We usually have breakfast in the cabins, well outside on the porch actually, where there is a large picnic table.
We usually buy groceries before we go, but if you need groceries there are two store on property, Meadow Trading Post and Settlement Trading Post. They are a bit expensive, though.
Transportation is not hard to figure out. From your cabin you are walking distance to an internal bus stop. There you will board a bus to either settlement or outpost. From Settlement (Pioneer Hall, Trail's End Restaurant :slurp: ), you can take a boat to MK, or a bus to TTC, MGM, and AK (not sure about AK). Outpost, which is the front desk, you board buses to Epcot and Downtown Disney. In the evening your bus brings you back to either Settlement or Outpost and you switch over to an internal bus going to your loop.
Your other transportation option is to rent a golf cart. You rent your golf cart from the Bike Barn near the Meadow trading post. You can park your cart in the front of your cabin at night and can take it to either one of the bus stops, where you must board a bus or boat to the parks. They do sell out quickly, so reserve one ahead of time or get their right when they open.
Probably gave you more info than you need, but if you have any more specific questions PM me.
Have fun - and try to get to the Hoop Dee Doo if you can.
