I've read the information and I'm trying to decide what to do. I'm going to be in London for 25 days. After the first five, I won't need to use the transportation on a daily basis, but I'll still need to. Would I be better served to just purchase an oyster card and have money on it for the duration? I'm confused about the fares--will it give me the cheapest fare as if I was buying a 7 day card, which is what I would do if I didn't buy the oyster card.
I'm going back next spring, so I am not worried about having a little bit of money left on it at the end should that happen. I'll just save it. I just don't want to be purchasing one day tickets and such all the time if there is a cheaper way to get fares.
I am uttterly confused.
