My girlfriend and I will be in Vegas in mid-March, and are planning on hiring a car to drive to San Francisco. We'd planned a route, but after reading this and other forums, it seems it would not be possible due to the weather conditions. I think I have a do-able alternative, but would like to get any advice anyone may have.

We leave Vegas early on a Monday morning, and have accommodation booked in San Francisco on the Thursday night, so have 4 days / 3 nights to make the drive. We're planning on heading out of Vegas to Death Valley via Pahrump and Shoshone, then take the CA-190 through DV and spend the night at Lone Pine. From there we planned to take the CA-120 across to Yosemite National Park, but I understand that won't be possible at that time of year? So instead, I'm thinking of heading all the way up to Lake Tahoe, to spend a night around that area. From here maybe take the US-50 and head south to spend our last night somewhere just west of Yosemite, so we can spend that last day heading over to Yosemite Valley, before driving to San Francisco.

So does that all sound viable? Thanks in advance!
