A friend and myself will be in Napa for the first time for three days at the end of August before traveling to San Francisco. We wanted to spend part of a day at a spa having a mud bath and taking advantage of the hot springs/mineral springs. Would anyone recommend Indian Springs or Dr. Wilkinson's over the other? It appears a similar Indian Springs package is about $100 more than Dr. Wilkinson's. Is Indian Springs worth that much more? Should we consider another spa entirely? My friend gets massages on a regular basis at home. I've only done the spa thing once before in Hot Springs, Sougth Dakota so I don't have many expectations but would like a good experience. Thanks for your input.
