I found this response to Norcal beach weddings on Yahoo answers...
I researched lots of venues on the ocean when planning my daughter's wedding. There aren't a lot of options, but here are a few you might consider:
If money is no object, you could try the Ritz-Carlton in Half Moon Bay. An absolutely spectacular setting on the ocean. The wedding can be indoors or out; the reception areas are gorgeous.
Also, if you're willing to travel to Monterey, any of the golf and country clubs along 17 Mile Drive have wedding packages. Pebble Beach is right on the water. But, very expensive.
A more reasonably priced option is the Best Western, the only hotel in Monterey that's right on the beach. They can do the wedding and reception on the beach or indoors.
A little closer than Monterey is Seascape Resort in Aptos. It's right on the water, too. http://www.herecomestheguide.com/locatio...
