I don't know if this works for the moderate or value resorts since there is a wall/window unit, but I read about this tip to control your thermostat in the deluxe reosrts:

Push power button and the temperature down button at the same time. You will see the letters "BP"where the temperature display is...then just sent the temperature to where you want.

Anyone ever tried?

Why would this make a difference, I'm not knocking it I'm just wondering what it does? I the moderates like Coronado, Carribean, and others you can control the temperature with the up and down buttons all the time. What does the "BP" mean? I looks like it stands for Barametric Pressure. The wall/window units are controlled through the thermostat on the wall.
