Been up there many times. You can do the Car Museum if your into cars. Not that big but worthwhile. If your into history you have to hit the Saratoga National Historic Park. Lots of revolutionary war history. Don't forget the horse races at Saratoga race track. One of the oldest in the country. They will be there until 9/7/15. If you want to drive a little try an hour north to Lake George...absolutely beautiful.
Have fun.
