Also you can look into motels around the NYS Thruway intersection with Rt 23.
Rt 23 has some motels on the way to Windham as well. And the town of Hunter is about 7 miles away, they have some motels too.
There should be plenty of available rooms in the summer.
Or rent a condo with the family (or friends) at Windham for the weekend, and stay right on the hill.
It's gonna be great, see you there.
