We are in San Francisco and looking for some location on California central coast, or inland, for December this year.

We got invited to presentation to Napa ts once while walking in San Francisco in the jazz festival area. Got 3 nights free. Our stay was great.

Also, for example, it's easy while in Las Vegas, various companies are pulling you in and then keep inviting to come over and over again. Looking for similar in San Francisco.
