Yep, they show “available by request” in several locations, but when you make it to the “read this before you book” link, it says:
Air Conditioning
Air conditioning is available upon request. As part of an energy conservation effort, air conditioning is only available from approximately 7PM to 6AM.
I love getting away from it all as much or more than anybody...but when the heat gets to me due to my MS, it makes me feel like somebody unplugged me from an outlet and let all the energy drain out. The only thing that really helps is cool water and cool AC when I get to that point.
