The Crown complex sprawls across two city blocks and includes three luxury hotels, top restaurants and a casino that’s open 24/7. It’s another world in its no-natural-light interior, where hours fly by. Thrown in for good measure are waterfalls, fireballs, cinemas and a variety of nightclubs. The complex is also home to luxury retailers, chain stores and speciality shops, as well as bars, cafes and a food hall.
