How long it takes from London to Paris by Eurostar?
I think that you should also think about prices. I assume that you are around thirty years old, which means that you would have to pay 59 pounds for a return ticket, and that is just a second class. First class tickets go from 139 pounds, which is a lot! At least for me it is. As for the time needed to cross the distance between London and Paris, it is around two and a half hours.
