My parents and grandma are visiting the US in the coming January. I've planned around 10 days in California: 2.5 days in San Fransisco, 2.5 days in Los Angeles, and the rest 5 days along the famous Highway 1.
I was told that 5 days on Highway 1 is really unnecessarily long, so I am considering adding one more destination. I've narrowed my options down to Lake Tahoe or Yosemite. Which is more suitable (in terms of scenery, convinience of driving, etc.) for winter visits?
P.S.: We will be driving a RV, if this matters.
