Yes, the 49ers will be there and you'll see a lot of RV's but DV never will be crowded because it's too big a place. make your reservations though at www.xanterra.com Furnace Creek Inn is most upmarket with lovely gradens and pool area. Furnace Creek Ranch is like a little village and Stove Pipewells is my personal favorite. Time of year is perfect for DV. Nobody knows if Tioga Pass is open or not. We had it open in december and closed in october sometime.
If open, us395 to Lee Vining and Tioga Pass to Yosemite would be my choice.
So maybe:
Day 1: Drive to DV.
Day 2: DV via Lone Pine and us395 to Lee Vining
Day 3: Lee Vining and Tioga Pass (beter to drive in the morning with the sun behind you) to Yosemite
Day 4: Yosemite NP
Day 5: Yosemite to Cambria
Day 6: Cambria along hw1 to Big Sur, Point Lobos SR, Monterey and to SF
If Tioga Pass is closed maybe try:
Day 1: Las Vegas to DVNP
Day 2: DVNP via Bakersfield to Oakhurst at the south entrance of Yosemite NP. Another option is to drive from DV to Three Rivers at the entrance of Sequoia-Kingts Canyon NP. And drive to Yosemite next day. Weather permitted.
Day 3: a. Yosemite NP
b. Sequoia NP-Yosemite NP
Day 4: a. Another day Yosemite NP
b: Only one full day Yosemite
Day 5: Drive to Cambria
Day 6: Drive to San Francisco.
You'll miss Solvang, Danish delight. Sorry about that.
If you want to visit Solvang, you'll prob miss Yosemite, but you'll have more time between Solvang and San Francisco. I would not want to miss Yosemite though.
If you think DV is too crowded for you, drive from Las Vegas via DV that day and see some of the sights on your way. You even could decide to stay at Panamint Springs Resort at the far west side of DV.
Yeehaw
