I'm booked on Dover - Calais at 0810 on Friday.
However, I'm thinking that an earlier ferry might be better so if I get to Dover early enough (there are earlier ferries at 05.55 and 07.20) then I will get an earlier ferry. I've a couple of things I could do with doing on the way if I get chance so an extra hour or two might come in handy.
I'm thinking a mix of RN and Autoroutes though - if you avoid the autoroute completely its about a six hour drive, use the autoroutes and it is about four.
My plan is (hopefully) to get to Thenay not too long after 3pm, have a bit of a mooch around, go off and find my hotel then come back at 6ish or something. Thats the (rough) plan anyway.
