The San Rafael area isn't as much fun as staying in San Francisco. It's a giant built-up and fairly old suburb. Maybe 40 minutes by car from SF.
However, just south of San Rafael is the Larkspur ferry terminal. The ferry is a quick ride to the SF Ferry Building right at the foot of Market St. Lots to do right there, and easy access to Muni , cabs, Uber. Lyft to get to Fishermans Wharf and Pier 39 tourist areas, Union Square, Chinatown. All places folks want to see, with lousy or expensive parking. The Exploratorium is a short walk up the waterfront and a neat place to wander around in.
Just a thought. [emoji8]
