<p>Can you do an open jaw airfare and fly into Reno (if you really want to do Tahoe) or Sacramento and fly out of SJC or SFO? I would really recommend flying into Sacramento if only to avoid the nasty Bay Area traffic. DV will be a stretch. I would pick either DV or Sequoia, not both. Plus there are so many cool things to do in and around SF i.e. wine country, the beaches, Santa Cruz, etc. Having spent a lot of time in the area and having been to DV, I would spend the remaining amount of time in SF proper. Save DV for when you do a Utah/Las Vegas type vacation.</p>
