London to Paris: Eurostar, Bus or Flight?

London to Paris is the classic European city hop, and the Eurostar makes it almost too easy: about two hours and twenty minutes from St Pancras to Gare du Nord, no airport in sight. Coaches are far cheaper if you have the time, and budget flights compete once transfers are added.
