Hi Dave
Welcome from a damp Twickenham.
I am also currently walking the Pembrokeshire Coast Path in stages (we started three years ago!). We walked the stretch between Fishguard and St. Dogmaels in September of this year. It's a fantastic section, in my view the best yet of this really dramatic coast path. You can see details of the stages we have done (where we were based and the buses etc.)
here . Just go to that intro page and click on the link to each Stage number to get a map and details of the route plus some low res. photos (sorry, I'm a rubbish photographer).
Looking forward to hearing more about your progress.
Cheers
John
