1. Ignoring Public Transport: The Mistake That Weighs on Your Pocket

Many tourists, especially those visiting London for the first time, fall into the trap of thinking that taxis and Uber are the best options for getting around.

The reality is that the city's public transport system is one of the most efficient in the world – and infinitely cheaper.

O Tube (London Underground) and the red double-decker buses cover practically the entire metropolitan area.

A day pass with the Oyster Card or contactless debit card costs on average £7-£12, depending on the areas you travel to.

In comparison, a single taxi ride from the airport to the city centre can cost in excess of £60.

Plus, the tube is almost always faster, as traffic in London can be chaotic, especially during rush hour.

Another common mistake is not downloading the Citymapper or the Google Maps to plan routes.

Some stations have different exits that can shorten (or lengthen) your journey significantly. If you don't prepare, you'll end up wasting time – and patience.
