Im currently planning a trip for five of us travelling down the westcoast of the US starting from Vancouver. Where doing this trip just after christmas so it will be winter time travelling.
While we have already decided to stop in Seattle and Portland, what i was wondering is where would be a popular or nice place to stop somewhere between Portland and San Fran to stay overnight in and break up the trip nicely.
I've had a rough look on maps to see what cities are about halfway between Portland and San Fran and was looking at around Crescent City, Ashland, Medford.... but have no idea what these places are like. We had been recommended visiting the redwood forest national parks on the way so if it close to that, that would be great to.
Any recommendations on cities to stop in or even places to stay would be most appreciated.

Thanking you.
