Tebunker, I'm getting married in April and we had almost decided to go to Prince Edward Island, Canada, but after looking at things a bit more we've decided to go to Mendocino, CA. We're flying into SF, renting a car and taking 128 to Mendocino (ranked in the top 5 of the best drives in the country), staying at a B&B in Mendocino for 3 days (right on the Pacific). Whale Watching, Deep Sea Fishing, Horse Back Riding and other activities are pretty reasonable there. Then we're driving back to SF, staying there one night to see the sights and coming home.
Just a thought, you may want to look at some other areas in CA as well
