Some Beach Somewhere..... Destination recommendations?

is any place within 1-2 days drive of the AZ or CA border that we could spend a week or two on the beach?

I believe you can cross the CA border south to the Baja at Tecate. That is Mex 3 that hooks up with Mex 1 south of the road closure.

We usually can easily get to San Quintin by the first afternoon. Next day, we can make it all the way to Bahia de Los Angeles on the Sea of Cortes side. Our favorite place right on the water is Daggett's Beach. No hookups - but warm sun, sandy beaches, and nice people.
