Napa Itinerary for a quick weekend in March

[mms43]

Hi,
My husband and I will be in St Helena for a weekend in March for a wedding at Merryvale. We would like some help formulating plans for us and another couple. There are so many places we would like to go but we do not want to cram too much into our short weekend. We enjoy great cabs, cab franc and sauvingnon blanc for the most part as well as great food. There are many things we would like to try: a great lunch spot in San Francisco, lunch at Pica Pica in the Oxbow Market or instead bringing a picnic lunch to a winery, Rombauer winery, Round Pond winery for olive oil and wine, Del Dotto winery, dinner at Terra or Market. Having a drink on the terrace of Auberge du Soleil also sounds nice. The only reservations we have is Del Dotto at 4 pm on Saturday afternoon. This is what we are planning:

Friday: fly in to SFO, have lunch somewhere great but casual
check in to hotel, go to Merryvale for wedding at night

Saturday: breakfast at hotel
winery (Rombauer?) around 10 or 10:30
picnic lunch ?
Round Pond winery
Del Dotto at 4pm
dinner at Terra or Market

Sunday: leave for airport

We would appreciate any thoughts or advice you may have on our itinerary! Thanks!
