From Napa I would drive over to Lake Tahoe, you could even stop in Sacramento and spend a night there looking around. It's an amazing place that hardly any Brits seem to go to.
When we went I looked into the drive from there to Vegas past the salt flats at Mono lake and along the east edge of Yosemite but we didn't have time to fit it all in. Apparently the route has quite a few gold rush era ghost towns nearby that I would love to have explored if we had the time.
Edit: Or it's only a short drive from Lake Tahoe to Reno where you could fly down to Vegas.
