I found Finger Lakes too busy.
Letchworth is great place to eat and visit in the fall ....but very very busy on the weekends.
Tip - Take American cash ...they don't accept cards for entrance.
Eat at the Glen Iris Inn and you get your entrance fee back and the food is very good.

What is good on a loop down there is Corning Glass Museum.

Food is good.. you learn the whole history of glass making and some of the stuff is mind bending.
