LI Wine Tours...please help!!

A friend of mine is moving back to NY after being gone for 2 years. I am so excited she's coming back I want to do something special. I thought a wine tour in late October/November would be the perfect thing to do. There are 5 or 6 of us who would go but I have NO idea where to being. Please let me know if there are any tours that you've been on before that are affordable ($100 range) and fun!! We would consider staying overnight too.

Thanks!!!
