I am staying at the BCV later this month, and am concerned about this too.
I had a room with one of these in Las Vegas, and HATED it, although I can certainly understand the value of it for the resort, I bet it saves them thousands and thousands in electricity.
However, it was really irksome to come in from the hot outdoors to a warm room.....I always loved the sensation of a blast of cold air when I'm overheated. I did not notice it being a problem at night in this room, however, I did stay in a hotel in MA that had this, too, and it was a problem at night, especially since I sleep the best in a cold room. The room would become uncomfortably warm, which would wake me up, I'd toss the bedcovers off of me, which would activate the AC, which would then make me cold, so I'd pull up the covers and fall back asleep, which would deactivate the AC, I'd get uncomfortably warm again, fling off the blankets....and, well, you get the picture.
