Look, it's expensive, takes forever with the queues, and the views aren't even that spectacular. You're stuck in a pod with strangers looking through scratched glass.

Here's what to do instead: Go to Sky Garden. It's free, same height, 360-degree views, and you can actually move around and get proper photos. Book online up to 3 weeks ahead.

Or just walk across Tower Bridge. Free, iconic Thames views, and you're not trapped in an overpriced tourist hamster wheel.
