Green Car Parking

[ianf]

The last couple of times I have been to Le Mans have been on organised trips.

We used the green car parks and pitched small tents on the Saturday with no problem.

Can we gain access to the car parks earlier in the week and what problems if any would we have in putting up tents.

Finally, (sorry new to all this) Whats the SP for Le Mans town on the Friday night?

Appreciate any help
