The London Pass®: 100+ Things To Do - Includes Tower Bridge

Well worth it, IF you're a good planner

We bought the 3-day pass for me, spouse and two teenagers, and can confirm it was a seemless experience and saved us a lot of money. Day 1: St. Paul's, Tower of London, Tower Bridge, then Uber boat to National Observatory in Greenwich. Day 2: Westminster Abbey, Churchill War Rooms (not included), and London Eye. Day 3: Arsenal Stadium tour and Hop-on-Hop-off bus all day. Even if the money were break even, it was useful to not have to stand in line for admission at each venue. We estimate we saved $300.

Worthwhile, but you still need to book for attractions

The London Pass was worthwhile, but we assumed that by getting the pass, we could just turn up somewhere and enter the relevant attraction. We arrived at the London Eye just before 10 am and were told we had to book, even though we had the pass. Whilst it was easy to make the booking, there were no gaps until midday, so we had to return a bit later. We also found some sights were easier to book than others. I'd use the London Pass again, but would book the sights 24 hours in advance.
