Actually when we stayed at the BC one year the bellman that brought our bags asked us if everything was ok with our room, and in fact I really was unhappy with the room and I said so and he said to call the front desk and tell them and ask to be moved.
The reasons I was less than thrilled with our room was that they were doing some refurb of the hallways right outside our room, complete with hammering,painting, drop cloths on the hall carpets, etc. The other thing which was not at all Disney's fault was that I had requested a ground floor room and we were assigned one at the FAR FAR end of the BC nearest to Epcot. It felt liked we walked 10 miles from the lobby! I knew that this was going to be a real hassle with the kids and going to the pool and back, etc. Plus it turns out that my DH does not like ground floor rooms! I guess we should have talked this over beforehand!! When I made my requests, I had no real idea of the BC layout. Now I would know to ask for a room near the lobby or at least the elevators.
In any event, I called the front desk and explained mainly about how the noisy work outside our room was unacceptable and I also asked if we could be moved closer to the lobby and on a higher floor. No problems, she offered me a choice of two rooms and we picked one on the 5th floor that was near the lobby elevators and was overlooking the bus stops. Still a standard view, but much better for us.
I never hesitate to ask for a room change if I am unhappy with the room. You are on vacation, you should be happy.
To answer your question, I would just say something like " we have gotten to our room and I see that we are overlooking a cemetary out our window (No joke here, that actually happened to us in a hotel in PA!) Do you have anything else available?"
