Hi Canesfan30!
Sorry This has taken so long but I've been digging out after our first big snowstorm of the season! Reality is not as much fun as Disney!
I thought the buses ran pretty smoothly (as my kids said we had good bus luck). As far as from resort to resort my method during regular hours is to use the nearest park. For example if I wanted take the boat to Mk and then the bus to the other resort. If it is a monorail resort, there is a launch (boat) from FW to the Contemporary the you can take the monorail from there. We did have a golf cart this trip which made within the campground and to the external buses a little quicker. Especially if you don't have a golf cart I would request a cabin in the beginning or end of a loop that you will be closest to the bus stops.
The cabins are well equipped. Obviously bring any food, drink, condiments etc. you need. Other things I can think of are a flashlight, a laundry bag and maybe some ziplock bags or plastic wrap (leftovers, cut fruit etc.) The other thing we bring is a 2 liter insulated drink container with a strap. Wal-mart has them for $5. We remove the inner platic bottle 1/2 fill it with water and put it in the freezer overnight. Before we leave for the park we fill it the rest of the way with water, zip it into its insulated case and we don't have to pay $2.50 for bottled water all day long. I will say we need two of these next trip.
During both of our stays at the cabins we have thought they were very quiet and comfortable. We didn't get to campfire/movie this trip. We camp alot so the campfire at FW is not a draw for my kids and there was only 1 or 2 movies my kids were interested in while we were there and other choices were made. We did do this in the past and would again in the future if it worked out. Make sure you bring a blanket or something it can get chilly sitting there in the off season!
I'm sure you'll have a great time at FW there is enough to do without going to the parks! The space and convenience of having a kitchen makes the cabins a great value in my book.
Let me know if I can help with anything else!
