Below is a link to cg's in that area.
Wineries.....I'd check into Canandaigua and Hammondsport area. Canandaigua has a new casino that's nice too (farmington), the downtown area (albeit busy) has some nice attractions, especially the food and wine institute. If you like camping in state/national parks, I'd seriously look into Letchworth park. You can easily daytrip to all the fingerlakes region/wineries from there, it's an AWESOME setting and a MASSIVE park...grand canyon of ny. The gorge, waterfalls, dam, wildlife, etc.,etc.
Depending on if you want "out of the way" cg's or not would be a determining factor in your decision coupled with when you plan on doing this. One things for sure...fall foliage ROCKS in the finger lakes region.
