Can you help me out to understand these three options?
I am arriving in London next Sunday...I know last minute!! There for 6 nights.
Planning on staying in London area for most of time, thinking of Bath on Londonwalks for Thursday, so need to get to Paddington station.
Plan to go to Greenwich, Buckingham Palace, Harrod's, Covent Garden, British Museum. Some with fees others not. Are these in zone 1-2 from my location, staying at Citizen M, near Tate Modern?
What should I do regarding purchasing one of these cards? Where do you purchase them, pick up in London?
Can you get some of this at the airport?
