Cook up??

Hi, I'm a GM newbie, just wondering how strict the 'no BBQ' rule is in the campsite? We've been to other family festivals, where they say no, but actually if you're careful and responsible the stewards turn a blind eye. Thanks all!

Tin foil barbecues (the disposable sort) aren't allowed, but ones that are raised off the ground should be OK. The group next to us had one last year.
