We'll be leaving Las Vegas the 9 May, driving to SFO. Would like to do Grand Canyon, Yosemite, maybe Death Valley. Would like to stop in Sonoma and/or Napa for a day & a night on our way to SFO. Arrive in SFO by the 12th or

We fly out of LAX on the evening of the 19th.

Would like this to be a relaxed trip. How much do you think we can fit in? Any recommendations as to what to see, scenic routes to take?

We are coming from New Zealand so who knows if we will have another opportunity to do this.

We could possibly shorten our stay in Las Vegas, we were planning on 6 nights, 5 days. Maybe we don't need that much time there?

Thanks for any feedback.
