Thanks Everyone
By weekend break, I guess you mean out on Saturday morning, back on Sunday evening?
No, it is looking like out on Saturday and back on Tuesday.
Looking around Google Maps it has become apparent that the Eifel, Mosel and Ardennes are all quite small and very close together so I am thinking we could probably check them all out probably using two hotels over the three nights.
Only pre-booking crossings early, will leave Hotel bookings to a few days before after the Weather has been checked out, or if the group is small (say four riders or less) we may just look for accomodation on arrival.
This leaves us a lot of flexibility to head to other areas if this region is going to be wet the whole weekend.
Plan B:- I know the Black Forest well enough and we can get there in one very long day, it's not much fun (8 hours in the saddle on UK and French Motorways) but worth it if the weather here is going to be fantastic and Plan A has gone belly up. If we stay on the French German border between Comar and Freiburg we are 30 minutes from either the Black Forest or Vosges.
Plan C:- Is the Morvan National Park, as all the other areas are at a similar latitude and only spread across 200 miles North to South and European weather tends to be in East - West fronts it is quite possible they could all be wet.
The Morvan park is about 150 miles further West, and a similar time from Calais, I have never been here, or heard much about it, but the roads look twisty enough and the wonders of Google Street view reveal what looks like OK surfaces and twisty (but not Alpine tight) roads in rolling countryside (and not much traffic)
Plan D:- Would be Normandy, would rather ride lesser roads in sunshine than "awesome" roads in the pissing rain, in my experience great roads in good weather can be pretty horrible in poor weather.
