Great advice from Paula. I'd add a few other suggestions... Whichever section of the resort you choose, request a room close to both the bus stop and the elevator. The buildings are large, and a room near the end of the halls can be a bit of a walk. In the same light, there are some buildings in each section that are close to the bus stops and some that aren't. That should help you when getting around within your section of the resort. (In the Grandstand, there's a compromise to consider. The building that's closest to the Carriage House is farthest from the bus stop. You'd have to weigh the options to decide which one you'd be going to most often.) For traveling between sections of the resort, you can rely on the buses if the walk is too far. Any theme park bus will get you to the Springs section, which is a short walk from the Carriage House and main pool. To get back to your section of the resort from the Springs, take the Downtown Disney bus. When you arrive at the Springs bus stop, you'll essentially be at ground level. The Carriage House is up a hill. The entrance is on the 2nd floor. While the slope of this path is ADA compliant, it's still a bit of a climb. There are also stairs from the pool up to the Carriage House as a second option. If both of these options are too much for you, head around to the left of the pool and toward the large green wall near the hot tub. There is an elevator through the set of doors in this area. (If going down, go in through the door to the Senses Spa.) Another thing to keep in mind if the walking gets to be too much, all
DVC resorts have a supply of wheelchairs that they'll lend out for the length of your stay. These are first-come/first-serve, but they'll usually have one. Not many people seem to know about them. There's no charge, but you do need to leave a security deposit. You can use it at the resort, or also take it on the bus to use at the parks.
