Hi, we are 2 couples in our early 50's heading to Guerneville for 2 nights next month. We would like a scenic drive from San Fran with some recommended things to do along the way. Then while in Guerneville, we would like to do some wine tasting. Looking for a recommendations on wineries to visit. We like dry reds and whites. Also if you can recommend a reasonable driver or tour company that is small and personal for wine tastings. Restaurant recommendations would be great too. Are there any natural hot springs in the area? We are staying at Applewood Inn while we are there. Thank you!
