We recommend staying near the wedding venue on Saturday in Sonoma County. We will be up in Sonoma ourselves from Friday-Monday, and will be in Sausalito the rest of the time. The event on Thursday will be in Sausalito, which is about 40 minutes from the wedding venue so we have listed some hotels in/near Sausalito as well for those who may want to come earlier and/or stay later nearby our home or stay Thursday evening near the location of the welcome party.
The properties we chose below are ones that we know and recommend and we have grouped them by HotelTonight's ratings(Kristin's previous workplace). Hint - Kristin would go for the Luxe - Brian would prefer the Hip :)
Airbnb (Another of Kristin's previous workplaces)is always a fantastic option for this area with many options. It is sure to have something for all budget ranges and accommodation needs, and especially great for families/large groups.
