Never been to a MotoGP there, but been to both car and bike 24hrs a time or two .......
Caen is closest, but the ride back to Roscoff is the best by far
overnight ferries out are always best, with a cabin
I would assume the camping arrangements are similar for the MotoGP as the 24hrs, and we usually use the "concentration" which is based in "Le Houx" section of the circuit. This is shown as the green area all along the back straights. This year we found a great spot, right at the very far end, just before the circuit goes back round to the start finish straight. New shower & toilet block adjacent, and good views of the back of the circuit
The benefit of "concentration", though it costs a little more than say the traditional brit area of Garage Rouge, is that the bike and helmet get stickers with matching numbers, and these are checked everytime you leave or enter the circuit. They also check ignition switches to make sure they haven't been forced. You also get free vouchers for a sandwich, beer/soft drink, and hot drink.
Once again, not sure if its the same, but at the 24hrs NO SHOP within a 10 mile radius is allowed to sell beer. This year they were also stopping people taking glass beer bottles into the campsites
We usually go to the intermarche at Eccommoy, south of Mulsanne towards Tours for beer supplies, and this year bought tins
Beer is sold in tins on th circuit/site, but is expensive.
There is a new tram link from the entrance to the Houx area direct into the town centre, so once camped and provisioned you shouldn't need to ue the bikes again ..... A trip into town on such weekends is usually quite entertaining in the town square/near the railway station
