I have spent a ton of time on looking at all of the different discounts and offers and actually bought a London Pass (then luckily was able to get a refund) and decided it was not for me. You may ask why? Well I started to do the math and realized that the only way I could do it is to go to a ton of their attractions but I also read the fine print. You can go ONE time - well what if I get to the Tower of London and it's cold and rainy and I only see half? I cannot go back on the ticket. In my research I realized that you could buy a membership to many of the attractions and get unlimited visits.
My biggest find was the Historic Royal Palaces. I had planned to visit Hampton Court, Tower of London, Banqueting House and Kensington Palace - yep they are all on the London Pass but again only one visit, if you do the math to see them its about 80 pounds per person (Banqueting House is still closed so I took that out) however for 89 pounds two people can get unlimited access to any of the 5 palaces. Why I like this is that I now do not have to cram everything into one visit or maybe I do but I have the option of returning if I want. If it was not during COVID I also could be getting extra perks and tours. But more importantly the funding goes directly to the charity and I feel especially in COVID times these charities need that extra money.
That got me looking at the other membership options and I am doing the same thing with St Pauls and Westminster Abbey - you literally can turn in your ticket for a membership and then if I want to pop back in I can but they are also getting very well needed funds. Once you take these big ticket items out of the mix, the London Pass no longer makes sense. Literally once I got my 1 year membership to HRPs I was going to have to go to every attracting in London to make it worth while. The only group that I could not make the math work is the English Heritage Foundation. They have an Overseas visitor pass but most of the places are not in London and so it just did not make sense to spend 69 pounds for two people for a nine day pass. Of all of their sites, Jewel Tower is the only one I planned to visit. But if you are travelling outside of London there are a ton of great options so I wanted to add it! There also is a 1 Year Pass that is part of the Royal Collection Trust where you can turn a purchased ticket into a year long pass. This is only for one site so it will work if you plan to go back more than once but it did not work for me
I do still have a few expensive items on the list and so I looked at the other options. There is a 2 for 1 that the Nationrail has operating. Basically if you have a rail ticket you can get a voucher that allows you to buy 2 tickets to a list of attractions for the price of 1. I admit that it sounds great but this is our first trip and the whole 'you have to buy a ticket' thing seems too complicated and I know most people are probably laughing but it has been hard enough to try and plan a vacation internationally while in the middle of a pandemic so I decided to pass on it.
I also looked at the Go City passes and you can do these by attraction. In looking at it I figured out what the cost per attration at each level and what I found is that for me since most of the big ticket items were taken by the above the only one that made sense was the 2 item passes to use for the Hop On Hop Off Bus and The Shard. Other than that - everything left on my list was under 10 pounds (by the way my keyboard does not have the Pound symbol which is quite annoying! I hope this helped - I realize this methodology does not work for all but I am glad I was able to find some of these.
