Visiting vineyards in Napa Valley...

[rden258]

I am planning my honeymoon for this october. We will be staying in Napa Valley for 3 days. One day we are planning take a 6 hour limo tour of some vineyards. From what I understand, we should have enough time to visit about 4 vineyards. Right now, I think we are definately planning on visiting Opus One, and Beringer. I am wondering what other ones might be fun/visitor friendly. Any suggestions on some of people's favorites? Any help is appreciated.

Thanks,
Randy
