I don't think any of them do. We also left the windows open and the ceiling fan on and it was quite comfortable. It doesn't get scorching hot there anyway, plus it seems like there's always a breeze outside.
Believe they all have thermostats. With the windows open you get a really nice cool breeze from the marina . if you get one with the jetted tub it's located right in front of 2 windows that give you the perfect breeze while in..
I dont know about any of the other cottages but the cottage we had cottage 20 with the jaccuzi does not have ac but it has a really great ceiling fan. Works so well I actually had to turn it off, it got so cold didnt even have to open any windows. We stated this past weekend it was really nice! Loved the jacuuzi tub. Used it every night, I highly recommend this cottage!
