Renting a Rally field or campsite for a party?

[JQ]

It's my 40th next year and rather than do the typical party or piss-up, we're looking at going camping for the weekend with the plan for mates and their kids to attend. As such there's the potential for there to be around 80 people in attendance. As such, most campsites won't be too happy with a large group turning up, plus we'd realistically want a whole field completely to ourselves and wouldn't want to upset other campers. We don't plan to have a disco, but with a large group I suspect we'd be louder than most campers.

Can anyone recommend any places that may be appropriate? We're in the North West, so the Lake District or North Wales would be preferable, but could go elsewhere for a good spot.

Cheers

No idea what this is like but large enough and just off the A55

This one has a separate field for caravan rallies but may be able to accommodate you
