Hotel says they are "green" and A/C turns off when you leave the room. We checked in and room was 80 degrees, this after we had been outside in 100 degree weather. It took 4 hours for the room to get to 79. We went to dinner, came back and the room was back at 80. We could not leave again, knowing the room would reset to 80 if we left. Info in room states that it resets to a temperature predetermined by the hotel. This is a money saving thing and not "green." Also, there was no A/C at all in the hallways.
