I’ve signed up! We’d have needed 6 for the discount which was probably optimistic.
Logistics wise you can fly to either Nice or Lyon, both about 130 to 200 return depending on dates then car rental is the only way to do travelling I think. But that’s very cheap over there. I’m not bringing my bike, it’s not set up for climbing and would be hassle to bring around. You can rent them over there, they’d have a fairly descent spec too. There’s a good bit of accommodation in the area but it might sell out. I’m thinking about just camping (not sure many would be keen for that).
