If your room is unclean or there is water pouring in or something, I'm sure Disney would be happy to move you.
If you would just rather be in another building/section, I doubt it. If they told you at check-in that it wasn't available, it probably isn't. But I don't know. Maybe they'll move people who complain - that would be very Disney-like.
Other than that, it's a hotel/motel. It's a room. There isn't a whole lot to be happy or unhappy about, I don't think.
