We're renting bikes and riding to Sausalito about 3 pm on Sat. 9/1. I know the place will be packed because of the Art Festival and I want to make sure we get to the ferry landing in time to make the 6:20 departure back to the SF Ferry Bldg. Will getting there l/2 hour early be enough time (I think the ferry holds 70 bikes)? I found an address that says the ferry landing is on Humboldt and Anchor off Bridgeway. Will there be clearly marked signs to get to it? If we only have 60-90 min. to spend in Sausalito, what area should we focus on (please list specific streets) for interesting shops, photo ops, etc. Thanks for the help.
