Have not used points for them but have stayed in the cabins before. They are small. There is a living room that leaves only a little room to move around in once you pull out the double-size couch, a little kitchen area with a table, one rather small bathroom, and then a bedroom with a queen bed and bunkbeds with only a little space to move about. No w/d. The reality is that the cabins were once (in the 1990s and before) just silver colored, mobile home trailers that then got covered with artificial logs to make them look like cabins; thus, particularly in width, their size is limited. Putting 6 in one is a real tight fit, particularly with only one small bathroom; putting four is OK.
If you have a car, you can park right at the cabin; however, as to driving internally, a car is of limited use, except for possibly a quick trip to the store that is about in the middle of the resort (a second store is at the Settlement Depot area), because parking space is very limited to non-existent for the activity areas of the resort. As far as going anywhere, other than by car, the resort has an internal bus system consisting of three different routes, so if using a bus, make sure you return to your cabin in the same designated bus that you used to get wherever you are.
All the internal buses go to the main activity areas: (a) the Outpost Depot at the south end where you enter the resort, from which Depot you can get buses to Disney Springs and water parks; (b) the Settlement Depot at the north end, which has the boat to MK, and another to Contemporary and WL, buses to the other theme parks and WL, Pioneer Hall with its Hoop Dee Doo review, Trail's End buffet restaurant (one of the best and priced somewhat less than other buffets at WDW), Crockett's Tavern (for drinks inside or out on the porch area. an excellent kid's playground, horse drawn carriage rides, a barn for getting pony rides, and the nearby Backyard Barbecue dinner with band; and (c) the Meadow Recreation area, in about the middle of the resort on the east side, which has the main pool, game areas, snack bar, and nearby is a place to rent bicycles and another place for the nightly Chip & Dale sing-along campfire.
For internal travel you can also rent a golf cart (I never did). You need to reserve one well in advance (they start taking reservations up to a year in advance).
The areas where the cabins are, and most of the resort is, heavily wooded. It is generally quiet in the cabin areas, and pleasant to actually walk around them. Animals such as racoons, deer, rabbits and armadillos can appear. Each cabin area is a loop where both sides end up at a street where the nearby, local bus stop will be located. The resort is an excellent place for kids, including because of the many activities provided, and excellent for adults who are not in a hurry, like quiet, like ease of access to Hoop Dee Doo and Backyard Barbecue, favor a good buffet with a somewhat lower price, like a horse drawn carriage ride, like taking the kids or grandkids to a campfire, and can sit outside Crockett Tavern with a brew while watching your kids or grandkids in the playground in that same area. As far as traveling to a park via the bus system, you always need to take the internal bus and then switch to an external bus (or boat to MK) and thus you should never assume you will be able to get to a park quickly.
