We are travelling to England in May for 5 weeks. We are having 4 full days in London and I was going to get an oyster card loaded with 20 pounds. How do I check how much money is left on the card. We are planning on either going out to Kew gardens or Hampton Court palace on one of the days also.
Our itinerary is to see the Tower of London, London Eye, do the big bus trip around london, Lords cricket Ground, and just wander and explore. Any other ideas would be great.
