May 3rd-6th, my wife and I will be making our first trip to Napa and San Fran. We hope to get to Napa by 4pm on the 3rd, stay the night of the 3rd and the 4th and then stay the night in San Fran on the 5th(our return flight is on the 6th at 2:40pm). We are hoping to do the Robert Mondavi tour late on the 3rd(either the 4pm tour or the 5pm Twilight tour), from there check into our hotel/Inn/B&B in Napa(recommendations on where to stay appreciated) and then head to downtown Napa for the night for dinner and take advantage of the Downtown Napa Wine Tasting Card. For our full day on the 5th, I am looking for a good itinerary for the day(my wife and I are wine novices and have just started enjoying wine, we both prefer whites over reds, but would like to get some variety). Would like to see as much as possible without feeling totally rushed. Then dinner and more time in downtown Napa that night. We will head back to San Fran on the morning of the 5th. Any help is appreciated!! Thanks in advance!!
