Get seriously high on Shanghai at the world’s tallest hotel, the Park Hyatt. Opened late 2008, the 174-room Park Hyatt stretches from the 79th to 93rd floors of the 492-meter Shanghai World Financial Center in Pudong.Calm, organic interiors feature flashes of mod-Chinese art and rooms come with floor butlers, free wi fi, espresso machines and daybeds for in-room spa treatments.Start the day with a tai chi session beside the 85th-floor infinity pool and end it with dinner and ballroom dancing at three-story Sky Tavern on the 91st-93rd floors.Ahh, the high life has indeed arrived in Shanghai thanks to Park Hyatt Shanghai.
