The fantasy begins in the lobby, where waterfalls spill into a pool stocked with flamingos and black swans. The lavish grounds wind around an 87,000-square-foot water wonderland with five pools and an extra-speedy, 128-foot-long waterslide. After enjoying the pool action (often rather noisy from the sound ricocheting off the hotel wings), hit the beach for snorkeling, stand-up paddling, kayaking, or parasailing (in season)—the sky truly is the limit. Recharge at Relish Burger Bistro, the poolside restaurant, but save your appetite for Wailele Polynesian Luau, the resort’s 3-hour luau experience that’s heavy on the fire-knife dancing. Stroll two doors down to shop at Whalers Village; when you’re ready to drop, your Westin Heavenly Bed offers no fewer than five different pillows and a divine mattress. If you need further revivifying, hit the Heavenly Spa for a Hualani fruit scrub and lomilomi massage. In keeping with Westin’s wellness theme, the hotel also offers a “mind and body” studio for yoga and meditation classes and a 2,000-square-foot fitness center, with loaner workout clothes at the ready, courtesy of New Balance.
