Hi there, Maureen!
Building 37 (in Alligator Bayou) is just adjacent to the North Depot bus stop on
Port Orleans Riverside property. It's toward the top right on the Resort map.
The construction is continuing on Alligator Bayou; the Cast Member to whom I spoke said that he anticipates work on building 37 will be finished on around December 16, 2011, just in time for the holidays.
I would call (407) W-DISNEY at your earliest convenience and speak to a Cast Member about this issue. You can communicate to him/her that you need to be near a bus stop, but because this Resort offers four bus stops. no room in more than a five-minute walk from complimentary transportation. In fact, you might request a room in Oak Manor, closest to the main Resort building (food court, shopping, bus stop).
Good luck; I know Disney will do everything to make this situation right for you and your traveling party.
See you later, celebrator,
