Why is the best room in the hotel called the Presidential Suite?

The Presidential Suite is a luxurious room used by high-star hotels to receive important guests such as foreign heads of state or senior business representatives. Its grand style, high grade and high house price are self-evident. Because of its unattainable position, ordinary people rarely have the opportunity to face-to-face contact with the presidential suite. The Wangfujing Hotel in Beijing and the Grand Hyatt Hotel in Shanghai, where President Bush stayed, are places frequented by Prince Charles.
