Marin Headlands Hostel

"Really, really liked it!"

Went here last weekend with a larger group and had a great time.  There are several family rooms as well as other options.  The kitchen, lounge room and game room are spacious.  Plenty of room for families with both younger and older kids.  A huge field in front to play in as well as a distant basketball court.  The only down side is the rooms are not well insulated, and noises can travel in the evening.  May make it challenging with a not sleeping through the night infant.  But if you have kids 6+ they could roam the place free (more or less).  Toddler - 6 y.o. probably needs to be watched more, but plenty of places to be and have fun.  The staff was very accommodating and helpful.  Nice to not need your own bedding and towels, very warm rooms, at least on the 2nd floor.  Also super close to the Bay Area Discovery Museum if your kids need a day just to be kids after many days on the road.
