Hope you have a fabulous time in Tenby, which site are you staying at? We're off to Pembrokeshire on 20th, hopefully???? Lets hope we get some good weather, lol.
Look forward to your review, we normally stay near Haverfordwest because we can visit the whole of Pembrokeshire from there but i have been looking at the Windmills site in Tenby, easy to walk into town in the evening for a meal and a drink :)
Haverdfordwest is not that far from Tenby , about a 20 min drive if you want to know anything about the area fire away and I will try and answer it for you I live near Pembroke Dock.
