Hello. I will have a couple of hours spare in London on Wednesday and would like to get a little more London coverage in. As a minimum the journey should go as follows (all national rail unless otherwise stated): Kings Cross -> Finsbury Park Finsbury Park -> Moorgate Moorgate -> Elephant and Castle (LU Northern line) Elephant and Castle -> St Pancras The question is would I be better of using my Oyster card or purchasing a paper off-peak day travelcard? With capping Oyster should be cheaper, but I've heard Oyster does some funny things when you have lots of journeys in a row. Will be travelling after 10:00, have a 16-25 railcard, and obviously an Oyster card with said railcard loaded onto it.
