Everyone’s first instinct is to grab the Gatwick Express from Victoria. It’s fast, it’s shiny, and it costs about the same as a small car. But here’s the kicker: you’re not at Victoria, are you? You’re at Heathrow.
So, you’d need to trek from LHR into central London first. That’s a solid hour on the Piccadilly Line. Then you’d wait for the Express. By the time you’re done, you’ve spent two hours and a mortgage payment. Hard pass.
