The High Roller in Las Vegas isn’t your average Ferris wheel. There’s nothing average about it. And it’s not really a Ferris wheel; it’s an observation wheel — the biggest in the world at a staggering 550 feet tall. The High Roller is comprised of 28 enclosed and air-conditioned transparent pods holding up to 40 passengers each. The pods are roomy with a couple of benches and the ride is smooth, not typically bothering those with a minor fear of heights.
