Sweeping vistas of the center of Las Vegas Boulevard are all well and good, but some of the best views you can get come when you’re lying on your back. Drai’s is no exception. The center-Strip roof deck offers plenty of hopping landscape to survey during dayclub hours, but it particularly comes alive at night, when you can kick your party up a notch by throwing in one of the house’s fireworks packages—$20,000 buys you 30 seconds of overhead pyrotechnics. For $100,000, you can push the show to two minutes. (Yeah, we don’t understand the math either …) At the Cromwell, 702-777-3800, DraisNightlife.com.
