The London Pass

Great idea if you're really well organised and stick to a timetable

Having the pass meant you didn't have to worry thinking about paying for bus or train fares (except outside the included area). It did mean that we had to plan really well to make sure we got the best value. The distance between venues, the time to see each sight properly and choosing only the included sights on the days of the pass were critical considerations. You really need to allow free days to see the other things not included though as there are many key sights that don't fit the pass. Overall if you have a limited time and are interested in a lot of the included places it is well worthwhile.
