Mr C and I did a 'heritage site' tour of Ireland a few years ago, and brought a B&B guide with us. We didn't book anything in advance, which gave us the freedom to go wherever we wanted and stay as long as we liked in each place. Most of the B&Bs were excellent - and we rarely went for anything above 3 stars in the guide. It was a great holiday, and one we might do again some year. I can't remember specific places we stayed on the west coast, though.
