Sheraton Waikiki’s multimillion-dollar renovations last year have turned it into an even plusher retreat. Though the beach is a step away, most guests spend their time at the resort’s Helumoa Playground, which includes a 15-foot high, 70-foot long water slide and two large whirlpools. Adults also love lounging in the hotel’s new infinity pool or sipping a mid-afternoon drink while listening to live music at RumFire’s happy hour. For dinner, choose between Twist at the Hanohano Room and its gorgeous Waikiki views or Kai Market and its tasty farm-to-table buffet. 2255 Kalakaua Ave., Waikiki, 922-4422, sheraton-waikiki.com.
