Thanks Southwest Dave! You know it all :)

By the way, I am really trying to fine tune my trip as suggested by you all and we may end up not doing the Death Valley/Vegas leg at all and in stead driving back to SF from Yosemite and then taking a flight to Phoenix or Page.

The trip is turning out to look more like this

Sept 25th - SF
Sept 26th - SF
Sept 27th - SF - Napa (one night)
Sept 28th - Napa to Lake Tahoe (one night)
Sept 29th - Lake Tahoe to Yosemite (2 nights)
Oct 1st - Yosemite to Fresno (drop of car) and take flight to Pheonix or Page where we will see Antelope Canyon, The Wave, spend night in friends place in PHX
Oct 2nd - Grand Canyon and Sedona
Oct 3rd - Fly home

What is the best/scenic route to go from Napa to Lake Tahoe to Yosemite and then Yosemite to Fresno? Is it possible to go through Gold Rush? Also, with this itinerary can we see Bodie and Lake Mono/Mammoth? Where do you suggest we stay in Napa and Lake Tahoe?

Is it possible to see Antelope Canyon and The Wave in one day?
