Sorry, should have said, Florence is the area we are thinking of. Last time we went we visited something like 16 sites in 6 weeks to catch all the venues we wanted to see - not just Florence, and, though enjoyable, it was hard work. Last year we went down the west coast of France and just stayed at 3 sites (apart from thre transit) and found it much more enjoyable.( Messanges I like) This time we thought we might explore Florencen from maybe 3 sites. East side of France seems expensive as far as tolls are concerned. Like the D roads better than the motorways but realised last time that you have to keep to the motorways in Italy as the other roads are so bad. Germany/Austria nice but the autobhans are scary. Have to buy a vignette(sp) I know but in Switzerland you have to buy two I believe - never been there. Dunkirk -Luxembourg sounds good.
Got the new 2014 map today so may have a look at that.
