It has been almost 20 years- time to go back for me. I am really envious. Lessee- hotels I cant help ya- we camped in the parking area where the Gendarmes tried to kick us out... things to do- Grand Marnier Crepes! Alors! those where great! Also, get paddock pass (we snuck in, but I'll bet you can't get away with that kinda stuff no more) so you can get a REAL understanding. Look into the tents and buildings in the infield- just walk on in- hell you don't speak French do ya? And try to get out early early to see the action as the sun rises. If you can still do it, go out over the pits and look down into the action. After 14 or 16 hours, people aren't neccessarily guarding their seats. You just might have to move around a little. Lastly, be ready to swarm the track (really!)lke everyone else
as soon as the winnning car crosses- someday someone will get nailed by the remaining contestants and it could be you...
Things to avoid? a feeling that you have to hurry- cause that won't be an option.
