I'm guessing the OP has already traveled. Just wanted to warn against taking strollers if you're travelling with an infant or a child who is stroller-bound and plan on taking the metro. Well, unless you want to do it comme les Parisiennes and schlep your strollers up and down a whole lot of stairs each time you get in and out of a station. Seriously no fun at all; get a baby carrier of some sorts or walk to spare yourself
