I've read the various comments, pro and con, about the cost/value of the pass. I will only be in London for three days. Arrive the last week of August after the bank holiday. With the short time in London, saving time by reducing the wait at key sights is more valuable to me than trying to figure out if I would save any money.
My question is: At the locations that indicate "Fast track" , do you really save time with by-passing people waiting in line, or is this just a markteting ploy. Any idea as to how much time is saved? I know it can vary, day by day, but a rough idea would be helpful. Any insight would be helpful. Thanks.
