nanaanpapa: "The problem with the Paris Metro is that it is not very friendly to people schlepping luggage, with many stairs and few, if any, elevators. It is a great system, but not if you are handling more than carryon luggage"
Very true! I tried it once and it was a nightmare, running my wheeled bag over people's feet, struggling to climb the stairs hauling a suitcase and a carryon on my shoulder. Never again for me.
The metro is great and I use it a lot in Paris, just not on arrival and departure.
