I don't know if this will work at the Disney resorts but I figured this out this weekend. The problem we've had is this: We like to sleep with the room cool. At home, the house is at about 66-68 from 12am-5am. In hotels, even though the thermostat would be set for 67, it would shut off well before the room is cool. At the hotel we were at this weekend(marriott at world center in orlando), the thermostat was just under the vent. So I changed the AUTO function to just ON. That way the room really was able to be cooled.
In the past, at PCR, I set it to a cool temp around dinner time. By bed time, it's cool in the room.
