So, to wrap it up: No, The O2 is not in the Congestion Zone. But you are sailing through the ULEZ waters. Please, for the love of your wallet, check your car’s registration number on the TfL website before you go. I didn’t, and I paid the stupid tax.
And you know what? Even with the fees, I still had a blast at the show. The O2 is a brilliant venue. But next time, I’m taking the train. Or I’ll get a zip card and pretend I’m a cool teenager again. Your call.
