Best cities/areas to visit in California for a romantic weekend vacation?

I am thinking about taking my boyfriend on a road trip up the coast. We live in San Diego so I want to head north for a few days. Some places I had in mind where San Fran, Catalina Island, San Simeon, San Luis Obispo. Anyone have any ideas? Oh and any worth wild places to check out, like I was thinking of going Hearst Castle, any other attractions we should stop for? Everyone is giving me a cities to visit but I need attractions too. I want to take him to special places we have never been before.

1. El Segundo
2. all the places you mention are great. Also, how about the wine country. sonoma/mendocino/napa? I would either choose the winw country (winery tours-free tastings and hot air balloon rides) or Catalina Island.
