Do something during the week, have fun together, sleep in a hotel, and just to have fun like to young girls going on a vacation together for a few days. out of New York. I don’t like new york especially in the summer.
Also consider Tannersville. Its a bit more heimish than Hunter, but only a 20 minutes away, so you can have access to the food / accomodations of Tannersville and the trails of Hunter.
