I am combining a business trip with my first time ever visit to Sonoma and am overwhelmed with the options for where to stay and what to do. Sonoma? Healdsburg? Yountville? Someone suggested a couple of nights in Sonoma and then to move up to Healdsburg. I will be traveling solo June 30th to July 4th. Has anyone done one of the Relish Culinary Adventures? Any advice to help sort out all of the options would be most appreciated.
