This high-roller's casino is replete with a rainforest atrium under a 100ft (30m) conservatory dome filled with jungle foliage, meandering streams and soothing cascades. Woven into this waterscape are scores of bromeliads. Exotic scents waft through the hotel lobby, with its 20,000-gallon saltwater aquarium harboring five dozen species of tropical critters from pufferfish to pygmy sharks.
