Bachelorette at Wineries....need advice!

I am planning a 'low-key' bachelorette party for my FSIL next weekend. I know she wants to go the the wineries on the north fork. I researched it and came up with 5 that I think sound great. BUT...5 is too many...I would like to get it down to 3-4 tops. Here are my choices...which would you choose or have you a favorite??

Osprey Dominion- Free/Guitar Soloist/Picnic Lunch area

Pugliese- Free/On a pond
Raphael-$8 pp/supposed to be gorgeous
Macari-$3 or $6pp/supposed to be beautiful
Martha Clara-Free/Live Music

We didn't choose PINDAR because we can drink their wine anywhere and we wanted to go someplace off the beaten path.

Go to all of them...They are all very nice
Also try Pelligrini

IMO Ospry is the best of the ones you listed

but you never stay at one...you winery hop

We just did this....we went to Pindar, Pelligrini, Martha Clara, Raphael, Castello di Berghese and Osprey's Dominion (that's where we ate lunch and where we had the most fun...wasn't crazy about the winery though).

My favorites were...

Martha Clara (cute shop, nice large room where the bar is)
Osprey's Dominion
Raphael (gorgeous!)

But we did 6 in 5-6 hours, so you might be ok with the 4 anyway.

Good luck!
