I've been to the Finger Lakes several times. The Finger Lakes are noted for their wineries.
Almost all of the wineries offer tastings, which I realize are not as interesting for the youngsters. (Although it may give them an introduction to alcohol in a better setting than any of their peers will get.) But some of the larger places also offer a short tour of their facilities, which is more likely to be interesting to everybody.
They grow almost exclusively white wine grapes, due to the cold winters. This hot summer will produce a great vintage year, if it keeps going.
There are a lot of excellent B&Bs up there, so you might consider doing that as a change from the usual hotel thing.
Cellar connection: while you are there, if you travel up route 96 out of Ithaca, you may notice a small shitty roadside bar called "Barangus". This bar was the inspiration for a (fictional) story by early dwellar Richh, who would have been a famous writer if he A) was less consumed with making every story incredibly pornographic, and B) hadn't died in his 30s.
