I know there have been several posts about this but I'm still having difficulty deciphering which one I should go with. I will be taking the Heathrow Express to Paddington Station then planning to take the tube for the week or so that I will be in London. Our hostel is near the London Eye, Big Ben, etc. but we plan to see Westminster Abbey, Tower of London, White Chapel, Covent Garden, King's Cross Station, really the main tourist things to see. We are three students so we're traveling on a bit of a budget and i'm also trying to incorporate the tube strike into my decision as we will be there May 3rd to the 9th.
