It depends on what resort you're at. At the BWI, the AC doesn't work on a motion senser, at the GF it does. If the sensor doesn't detect someone in the room, it doesn't matter what the digital setting has been put on, it defaults to something like 74. When we used to stay at the GF, this was a huge problem for us. I love the heat outside, not inside. These thermostats were put in during the room refurbishment.
We called concierge and they told us that someone would adjust the default temperture for us (I think we kept it at 68). It only lasts 3 days though, then you have to call and have it reset. By the way, they will do this in any room, not just concierge. For a long stay like we always have, it was was a bit of a pain though (we hated to keep bothering them).
