Sharon and I tend to be very agressive about covering lots of ground when we travel. Two years ago, We covered 1,500 miles in fifteen days exploring Florida. On the France trip, I esimate that we covered more than 1,600 miles in 14 days. We traveled about 750 miles by train and almost 850 miles by car. Admittedly, this included two big travel days: Reims to Chamonix and then Chamonix to Sancerre.
In spite of the effort to get to Chamonix, we felt that it was definitely worth the trouble. From my perspective, the French Alps were unlike anything I have ever seen. Standing on the floor of the narrow valley and looking up at peaks on either side that rose more than 10,000 above you with a couple of big glaciers was amazing. It rivaled the experience of the Eiffel Tower, the Lourve and the other major tourist destinations.
On the other side of the coin, we spent too long in the Loire Valley. Two days would have been enough to accomplish what we wanted to do.
I also wish that we had spent more time in Paris. While we had a chance to explore the Rue Cler and Montmartre neighborhoods a little, I would have liked to have had a some more time for some of the walking tours in the guidebooks.
