Thank you for the replies!!!!
Have put in more details to my intinerary.
Here it is:
D1: Arrive SF at 21:15H
D2: Fly SF to LAS, pick up rental car
D3: LAS to Zion NP (Overnight@Springdale)
D4: Zion NP to Bryce (Overnight@Bryce)
D5: Bryce to Page (Overnight@Page)
D6: Page to Grand canyon south rim (overnight@GCV)
D7: GC to Hoover Dam to LAS
D8: Fly LAS to SFO, pick up car and drive to monterey (overnight@monterey)
D9: Monterey/ Carmel (overnight@monterey)
D10: Monterey to Big Sur to Cambria (including Hearst castle) (overnight@cambria)
D11: Cambria to Paso Robles, stop at Fresno for lunch and groceries, then on to Yosemite (overnight at Yosemite west apt)
D12: Yosemite NP (overnight at Yosemite west)
D13: Yosemite to SF (maybe pass thru Berkeley)
D14: SF (inc Alcatraz Island)
D15: SF
D16: Depart home
How does this sound?
Should I keep the car until we fly back home? Or drop it off when we reach SF from Yosemite?
Any personal favourites in terms of accommodations/ restaurants?
Should I just omit the Pacific Highway route on D8 to 11 so that I can have more days in SF/ LV and cut down on the driving?
