Bummer. I'd be very happy to hear suggestions for other great places to visit/stay. Is Cambria nice? Where's a good place to stay in Carmel? Thanks.
I'd stop in San Luis Obispo. It's a little in from the coast so not as foggy as the towns right on the water. Nice small college town with plenty of restaurants, hotels, local shops.
