The official meet hotel for the Falls Classic is the Home 2 Suites in Henrietta, New York. They are holding a block of 25 rooms for $109 until AUGUST 15TH. Mention OUSA orienteering when you call to book a room.

Heard from a couple of people who said the link worked well. This is a new hotel so it should be pretty nice.
