That's a lot of territory to cover in 3-5 days. Too much driving, in my opinion.
I would choose either:
Northern California = Bay Area-Monterey<->Yosemite/Sequioa, or
Southern California = San Diego-Santa Barbara-LA
Regardless what you choose, if I'm around when you're in Monterey, I'd be happy to get you and your wife into the Monterey Bay Aquarium with guest passes.
Congratulations on 44+ years together!
