Hi Jen and welcome from an English woman now living in France!
I spent many happy holidays as a young teen, water skiing in Abersoch, which I think is just below you on the Lleyn? I remember once going on a day trip to Llanfairpwyllgwyn...gogogoch etc, you know the one, can't spell the rest of it, although it's my 'party piece' that I can say it! :D
Tisha - I lived near Haverfordwest for two years when my Dad was working at Milford Haven, in a little village called Roche where there's a castle. It was 1971-73! And you're right - the Pembrokeshire coastline is beautiful - all those 'Havens'! :D
It's great here Jen - I'm sure you'll find all the advicce and inspiration you need as well as boundless encouragement and support so ask away and don't forget - we LOVE pictures! :D
