Thanks for all the great tips.
The Inn looks great and I'm happy we'll be there for the full moon. I agree with Martin that the issue is what to leave out, I prefer to focus on a few areas of interest rather than a scatter gun approach - there's always next year. We're lucky that our boy isn't in school yet so we can get away outside of school holidays. This is really a family trip not a photo trip but my wife likes these areas and she's fond of the idea of a picnic on the cliffs as the sun goes down (let's hope she can set up next to my tripod!).
Are there any Neolithic remains close by?
