Two couples in their early 30's looking for recommendations for a place to stay, wineries to visit, great restaurants, and a nearby golf course. Planning to stay a weekend in early June

Try fingerlakes.org You may want to stay in Seneca Falls. Pretty quaint little town. The Fingerlakes area is so very pretty. I'd never done a wine tour, but we've taken our Harley all around the Finger Lakes area.

Have a look at www.belhurstcastle.com. We have stayed there twice in the actual castle. Now they have a winery on site and a new in attached next door. It is in Geneva New York. For golfing you may want to check out Bristol Harbor. It may be a bit of a drive but the back nine is worth it.
PS. In the castle on the second floor there is a spiget with free flowing wine for guests. Look it up.

Sorry on the last post. Meant to type "inn attached next door"

I don't know anything about golf-because my time in the Finger Lakes involves water activity mostly but...
Hammondsport and Ithaca both are nice places to stay. I also like Corning for the museum and gift shop.
Also a nice place to stay or eat is Taughannock Farms Inn outside Ithaca. From there you can go to the gorge and visit the fantastic waterfall in the park.

Skaneateles is great. Stay at the Sherwood Inn, or Mirbeau Inn/Spa, and go to Rosalie's Cucina for dinner. Quaint village, beautiful lake. If you head towards Syracuse, there's a bunch of golf courses to choose from.

All great advice so far! Skaneateles is a far way from wineries -- you will want to stay on Seneca or Cayuga so you're not driving really far after wine tasting.

For early 30's, I would look at Ithaca, however can't give advice on golfing...anywhere!

This months issue of "Wine Spectator" has a comprehensive article on visiting the Finger Lakes, I would definitely buy it if I were you, it has great information.
