NEED ADVICE! SFO to LA to Vegas and back in 11 days

[Paipo]

Hi, I'm planning a 10 day roadtrip at the beginning of April (1-11). The idea is to go from San Francisco to LA, then to Las Vegas, and return through the Death Valley and Yosemite National Park to San Francisco.
Do you think it is a bit early in the year to do this?
I would need some answers quickly because I have to buy the plane tickets from Spain, so I would appreciate your answers very much.
Thanks!!!

Yes, it is a bit early (at least for the DIRECT route from Death Valley to Yosemite), but with ten days, you will be able to get to all your destinations by alternative roads. It'll just be a few extra miles. You won't have any trouble on the rest of the route.
