South wales campsites?

[WhirlwindHugs]

We're planning to go camping with my sister and her family this summer, we want to go in the UK (because, cheaper) South Wales, or Devon/Cornwall type places. Sister wants France because of the sun and better camping facilities (pools, on site games, nice shower blocks etc)

Obviously we can't do anything about the weather! But can anyone suggest somewhere in the UK with really nice facilities to try and tempt her with .

Oh, also we have three young children so needs to be child friendly. A little play park would be nice but not really looking for entertainment in the evening type set ups.

This isn't at all what you've asked, but it is in Wales and it's very child friendly. We went year and loved it. naturesbase

That looks fantastic for us (definitely going on our list, thanks for the link!) but farms probably not going to appeal to my sister.
