Landing at Paris' Charles de Gaulle airport brings such excitement and exhilaration after a long flight. That can quickly fade after waiting to get through customs, using the restroom, getting cash at the ATM, ordering generic coffee at the mini-café at Charles de Gaulle (you know the one), searching for your luggage at baggage claim and fighting traffic into Paris' city center. Ugh.

That's a general plan of attack for anyone who is fresh off an international flight to Paris. But once you get into the city, the fun begins.
