We are thinking about staying in Tiburon for 2 nights and spending our one full day taking the ferry into San Francisco, seeing the sites then back at the end of the day. I am worried that the last ferry seems to leave Tiburon at 8:45. Then after that there is no ferry service until after 4 pm? If we miss the last ferry out of Tiberon (and with 2 small kids that could happen) are we stuck? We want to stay here to get away from some of the crowds, also we are traveling with a couple in an RV. Is there anywhere for them to camp in Tiberon? Any advice on any of this would be greatly appreciated. We will be staying Aug. 12 - 14, 2009.
