Not really a trip report, but just a mini update in case anyone is planning for a larger group. I just returned from a long weekend with a group of 15.
We stayed at the Chauvet and catered a couple of meals for the Glen Ellen Village Market. The entire group took a tram tour at Benziger and a family style dinner at the Glen Ellen Star.
Reviews are under the individual listings, but hopefully this is a helpful starting place for anyone else in the same position I was for planning!
