We are spending three days in London. I plan to get my husband and me oyster cards with 15 pounds each on them. I remember reading about getting an oyster card for my son for only 5 pounds. Well, as I'm going over my itinerary one last time, I realize I was supposed to do this 3 weeks in advance. Am I now stuck with doing the same thing for him (15 pound oyster cards)? Or is there another discount I may be missing?
We are flying into Gatwick and taking the Gatwick Express to Victoria Station. We are staying in the Covent Garden area. We plan to use the tube and bus for the most part to see the Westminster area, Trafalgar Square, Imperial War Museum, Tower of London, Beatles Walking Tour, British Museum & Library, and Harrods over those three days (if possible). Are the oyster cards the best option for us? Or would it be about the same to use taxis?
