The fantasy begins in the lobby, where waterfalls spill into pools 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 water slide. (I screamed the first time I flew down it.) After enjoying the pool action (waterfalls, aquatic basketball, volleyball), hit the beach for snorkeling, stand-up paddling, kayaking, or parasailing . . . the sky truly is the limit. Recharge at Relish Burger Bistro, the poolside restaurant, but save your appetite for Wailele, the resort’s 3-hour luau experience. (Kids can get an all-day dining pass for $20.) Stroll two doors down to shop ’til you drop at Whalers Village. Return to your room to sink into your fabulous Heavenly Bed, a Westin trademark, with no fewer than five different pillows. If you need further refreshment, hit the Heavenly Spa for a Hualani fruit scrub and lomilomi massage—I highly recommend it. There’s also a “mind and body” studio for yoga and meditation classes, as well as a 2,000-square-foot fitness center. Forgot your workout clothes? No problem. You can borrow a set provided by New Balance.
