All the cabin loops are located together, up near the main entrance to the campground. There are no cabin loops down by the restaurant, store or marina. You have to rely on the buses or rent a golf cart to get you down to that area. If you're just looking to be close to the pool or the laundry area for the cabins, loops 2500 or 2600 are probably your best bet. I know there is a cabin down in the 100 loop (closest to everything), but I don't know what the story is with it. I'm not sure if it's available to rent or if Disney has some special purpose for it, but I suppose it's worth checking out
If you are getting a handicapped accessible cabin you will not have a choice of loop. Sorry but they are all in the same loop. Unless the added and moved them into 2 loops they will be in loop 2800 which is where they were as handicapped homes.
If you are getting a standard cabin then loops 2400, 2500 and 2600 are closet to the pool and laundry area. You will need a golf cart or the bus to get to the Meadows and Pioneer Hall areas where the other activities are located.
