We will be driving from SF to Las Vegas at the beginning of April, spending one night on the way. We had originally planned to stop overnight at Mammoth Lakes but have changed our minds after finding out that the Tioga Pass will be closed in April. We still want to visit Yosemite, so can anyone recommend the best route and where to stay overnight, obviously we want to get as far as possible but without driving for too many hours. Also, is it possible to visit Death Valley on the way to Vegas if you are coming along the southern route from Bakersfield? Any advice or suggestions would be gratefully received.
