I am thinking about renting at the Lodges at Cresthaven but the only date available is the week of October 18th, 2009. I have never been to upstate ny before and am wondering if the attractions will all be closed and I should consider going earlier in October. I am trying to go for the fall folliage but would not like to get there and everything be closed. Can anyone give me any information on whether the attractions in the area will be closed?? Thank you for any feedback.
