Well I know Mario fixed the guy up for the 3 of us on the 1 site, cause I remember mario saying it was like $20 extra for rob.
As for the other sites, well i wouldn't have the foggiest idea.. Unless he believes the 4 people that were sitting with us (Jase + 4) were staying in our sites, then obviously they're incorrect, perhaps it's is a misunderstanding otherwise my only guess is that everyone paid, perhaps he feels not for the correct number of people per site...
As for the behaviour, I can only think of that 1 situation mentioned above.
There was some carry on out the front of the park or around the corner with some car crashing into what sounded like garbage bins, which we were all woken by.
We may have been abit boistrous but certainly now noiser than when dave was down for last years GP. Mario was only pissed and carrying on 1 (sat or sun) night... not the thur, fri, sat and sunday nights he carried on last year

hahahahaha Sorry Mario
So it sounds like were back to the issue Duane had with trying to make a group booking.. Only difference being he knows the name of a group he can identify to try to stop group bookings.. Hi call i guess, but he doesn't seem to get fully booked, so his loss at the end of the day.
Perhaps a block a land for the weekend... Toilets would be the only 1 issue..
