Camping Uk

I’m looking to find any caravan parks that would be willing to accept a large group of young people aged between 16-20.

Preferably South West England or Wales

Any information would be greatly appreciated.
Thanks for the butlins tip but some of our group members are 16 + 17.

Can you please try to include website adresses in your answers or contact details for parks themselves.

Wanting to go away for xmas

would need to be good for kids aged 3 - 14 and all inclusive, like butlins
