Whether or not you'll get to ride a doubledecker bus when taking the London buses does somewhat depend on your route, but if you're in central London (like Piccadilly Circus, above) you're likely to be able to grab a doubledecker. Get an Oyster card and hop on a double decker bus -- matters not where you go because you're along for the ride.
Where to Sit on a London Doubledecker BusYou want to sit on the top deck of a doubledecker bus, of course -- that's the fun! The stairs are behind the driver, who sits on the right. You may see a small TV screen behind the stairs; it may pan the top floor (or it may just show soccer games) if you want to ensure a seat is open before you climb.
