I can do one way on SW instead of R/T. Will be getting rental and have not done different return point before and do not want to pay an exorbitant amount for that option. Was thinking of spending one night in Monterey and see Big Sur with the rest of the trip open. If weather allows would like to see Sequoia National Park since I have always wanted to see the redwoods. Trip is open at this time and I am just looking for suggestions. Trying to plan romantic trip with sightseeing.
