Fine. If you want a ridiculous entrance, you can take the IFS Cloud Cable Car from Royal Docks. It flies over the Thames. You’ll see the O2 from the sky. It’s like arriving like a celebrity.
But here’s the catch: it doesn’t go to the arena. It lands on the other side. You still need to walk 15 minutes or get a shuttle. So unless you’re chasing Instagram glory, stick to the train.
I’m just saying: don’t overcomplicate things.
