Shades of Green used to be the Disney Inn but is now a military hotel run by the Armed Forces. Active and Retired military can stay at awesome prices! (we were there Feb 2002 for $95 a night). Rooms are huge and sleep 5 comfortably, and there is an awesome laundry room also.
Right now the hotel is undergoing a major renovation/expansion, so all Shades of Green guests are actually being housed in the Contemporary for now.
I know there is an official website for Shades of Green but lost it when we switched computers, but if you're interested you could probably do a search and find it, or maybe someone else on this board has it.
hope this helps!
