I would take them to the former. But if you have time the coast is always a winner. You might not have the time but I took a friend from Germany to Pigeon Point Lighthouse and then down through Pacific Grove 17 Mile Drive and Big Sur that’s always a winner.
Yeah, Umunhum is an afternoon trip
Carmel, Mission Ranch with sheep, Carmel Mission and Bixby Bridge is the planned day trip
Thnx
