We're going to drive from Bordeaux to Alsace this summer, and I'd like to "play it by ear:" touring the countryside, stopping off at especially charming places and picking our lodgings as we go. I understand this could be a little fraught in late July and early August, but that's the time window we've got. Question: does one week seem like a reasonable allowance to accomplish this?
We haven't yet decided where in Alsace we'll be staying, but probably among Metz, Strasbourg and Nancy. Any recommendations as to which city?
