I just got back from Pop Century and their thermostats also do not go below 68. I thought I was the only one that woke up sweating at night! It should have been cool enough but I have no idea what they do during the night that makes the temp NOT stay at 68. I would sleep in a tank top and undies and just the sheet (so my kids were not traumatized by my sleepwear) and I was roasting. By the time we got up in the morning the room had cooled back down and was actually chilly!
