Despite the name, the wedding venue is not an actual hotel.
If you're coming from out of town or simply plan to enjoy the delicious beer, wine, and bubbles flowing at the wedding we recommend staying overnight. Initial research has shown that because of the season many hotels require a 2-night minimum. Consider making it a weekend trip.

Petaluma may be more economical but involves a 20-25 minute drive over two lane and somewhat windy back-roads.
We've had friends book in Rohnert Park (35 minutes) and also consider Napa (25 minutes) and Novato (30 minutes)
