1. Grand Hyatt

Pool day pass: HK$550
The luxurious 50 metre pool at Grand Hyatt brings tropical vibes against Central's sea of skyscrapers. Arguably one of the best pool day passes in town, the package also includes access to the hotel's gym and sauna.
After you've worked up an appetite, the famous poolside buffet at The Grill is a welcome treat. Or, on the same floor—but unincluded in the package—is Plateau Spa, where bustling urbanites can choose from 61 indulgent treatments.
