Paris in a day

We woke at 7:30 and walked from our hotel in Les Halles to breakfast somewhere in the neighborhoood, espresso and a croissant, then to the Louvre for 2 hours, capped by 300 sweaty stinky humans roiling in a mona lisa rumpus, then exhausted, lunch at CafeRuc, the foie gras for me and the omelette for lady courtenay, then up to the Palais Royale and right back down and out to the Ile de la Cite for Notre Dame and then out to the Ste. Chapelle and then from there along the Seine to the Eiffel Tower and then from there to the Arc de Triomphe and from there down champs elysees past the place du concorde and back along the seine to our hotel again by 6. 10 hours almost nonstop except for a quick breakfast, a quick lunch, and a pee and a coke zero at a bar along the way. According to our calculations it was 20 miles at least.
