Challenge: San Francisco, CA and surrounding areas

I spent a week this past February exploring San Francisco and the surround areas with my husband, and we absolutely fell in love with the region!  We were warned by several people about chilly weather, but since we were coming from winter in Ohio we thought it was beautiful outside!
This is a slightly different format.  I have select three areas for 2-night stays.  These can either be used separately as weekend trips or all three options could be combined into a week-long trip.

Criteria: These are 2-night trips priced on travel from San Francisco, CA
