I appreciate that this indicates a vast lack of understanding about the ACO but won't they just for once think about the bloody fans. 
Actually, I would suggest that this is exactly what the ACO are doing.
Over the years, myself and several of my friends have had the problem of arriving on a Thursday with legitimally purchased tickets, only to be told at the camp entrance the site is full. We have then had to endure arguements untill finally being allowed in, whereby of course it is damn near impossible to find space to camp together, whilst those that arrive earlier in the week have huge areas roped off just for their paddling pools and stuff.
It is why I now only use Houx, and several of my friends no longer attend the race.
I appreciate that not everyone takes up too much space, and indeed, they buy enough tickets to cover what they want, but this does not apply to all. What can be fairer than having a premarked and numbered space which you know will be waiting for you even if you can only arrive Friday afternoon?
I think this should have been implemented several years ago, and personally I am really looking forward to the possibility of returning to MB with a group again.
