Hello Lisa,
I really should have looked at some of the other posts. I think ChrisAPs` itinery is ideal - if people are going to make an effort to travel, then I imagine most would expect at least one overnight stay. The idea of a "photogenic" location makes sense. Believe it or not I`ve never had a complete days photography, come to think about, probably not even a half day, so if I were to make the effort to travel I would like some time taking pictures.
By the way I was being cheeky suggesting the Brecon Beacons, I know the area well as I can see them from my house on a clear day! Strangely, since I bought a camera, over two years ago, I have never taken a single picure there.
Chris
