If you’re buying tickets, the “capacity” tells you how crazy the atmosphere will be. At 20,000, the crowd roar is deafening—in a good way. But you also have a good chance of getting a decent view.
Next time you see a band play The O2, whisper to your friend, “Remember, there are 20,000 of us in here.” It makes the concert feel even more special. You’re part of a small-town-sized party.
So, is it the biggest arena in the world? Far from it. But is it the perfect, friendly size for a world-class show? Absolutely. Just don’t forget to buy a souvenir; you’re one in 20,000, after all.
