Lots of wineries and craft breweries in the Keuka & Seneca Lake areas if that floats your boat. I have visited Keuka Lake a number of times and there are plenty of places to visit. A possible accommodation location is the Esperanza Mansion in Branchport: http://www.esperanzamansion.com/ overlooking the lake.
There is the Curtiss Aviation Museum in Hammondsport. Also lots happening in the area: http://www.keukalake.com/
