I dont mind playing a part as i said i usually have several car any how
The thing to do is book say 10 or 20 camping spots now
Le Mans then contact you in the new year and say this is what we have given you not always what you wanted mind!!
Then you have 21 days i think to pay for your Camping spots or loose them
Once you know where and who is going try to crack a deal on crossings
Buy the General entry ticket at the gate in Euros gets you in for the whole week
Relax and enjoy
I figured last year in the Evo
