In need of affordable multi-family resort near Bay Area
We are planning a large family reunion that would probably be 40-45 people coming from all over the U.S. but would need to be somewhere easily drivable from the Bay Area (Oakland and Davis) where the oldest members of the family live. Looking for a resort or something similar that is affordable, with a good large communal space as well as either kitchen facilities or a restaurant on site, and that feels like a getaway. Whenever I search for these amenities I come up with yucky conference centers that look like airport Hiltons in places like Vallejo. I've thought about vacation homes at the Russian River or similar, but it would be too hard to do communal meals or other activities for this big a group at private homes. Any suggestions?
