Just back from 17 days in France...it was simply divine.  3 days in Paris, Aix en Provence, then a river boat trip through Normandy.  I really liked the river boat, which was a surprise...it saves the hassle of a car and stopping in every little town along the Seine was just wonderful.  If you want to take day excursions farther afield, it's easy enough via taxi or tour....planning the next adventure now!  Lyon and Spain.
