Superb work...!
As commentated before, I would not be upset to miss Le Mans Classic and/or Le Bounty. Could we drop in on our way through, to say hello and/or have a pint of Pride?
For me, A and H should be one-nighters (and could H be a bit further south? Looks like a short drive on that last day or could it offer a pre-Ferry look at the Normandy beaches which I'd really enjoy?)
Despite the short drive the previous day, C should be a definite two-nighter to allow an excursion into Porto (had a week there the year before last on a wine tour - superb town)
We also did a Ribera del Duero wine tour based in Valladolid years ago (you may be noticing a theme with how we holiday!), so would suggest that D be two nights too, again with opportunities for a nice excursion!
re D and F... are there any wineries that have accommodation (and good catering)? That'd offer a superb base for a two-nighter!
Otherwise... don't really care!
