First, the views are unbeatable. You see the Thames Barrier in the distance, which looks like a giant metal caterpillar that decided to nap in the river. You also pass under the Emirates Air Line cable car—try to wave at the people dangling above. They're usually too busy taking selfies to notice.
Second, it's faster than you think. The tube from Hilton Docklands to Canary Wharf involves a train change and some confusing hallways. The boat is direct, simple, and doesn't smell like someone's leftover pasty.
Third, it's cheap! A single fare is about the same as a tube ticket, but you get fresh air and a show. That's a bargain.
When to Do It for Maximum Effect
Go at sunset. Yes, I sound like a greeting card, but trust me. The sky turns pink and orange, the glass buildings reflect it all, and you'll literally gasp. It's better than a therapy session, and you don't have to talk about your childhood.
Or go on a sunny morning. The water sparkles like someone spilled glitter, and the seagulls look slightly less angry. It's the perfect antidote to a boring commute.

Bonus: if you take the last boat, the city lights come on, and Canary Wharf looks like a futuristic wonderland. You half-expect a spaceship to land on the rooftop of One Canada Square.
