Hamburg, Mar 1 : The JW Marriott Marquis Dubai, which opened this week, may hold the new record for the world's tallest hotel building, but there are several other hotels that have breached the 400 metre mark.

All the rooms in the Ritz-Carlton in Hong Kong are to be found on floors with three-digit numbers, and offer a magnificent view of Victoria Harbour and the city's skyline from well over 400 meters up.

The very highest luxury, in a twofold sense, is enjoyed by guests staying in the 415 sq. m Ritz-Carlton Suite on the 117th floor.

A research by Emporis (www. emporis. com), the international provider of building data, shows that the Park Hyatt Shanghai is located on floors 79 to 93 of the Shanghai World Financial Center, the city's tallest building at a height of 492 meters and a total 101 stories; in Shenzhen, the top 26 floors of the 442 meter tall KK100 are home to a St. Regis-Hotel.

At 355 meters in height, the JW Marriott Marquis Dubai, supersedes the 22 meters shorter Rose Tower, home to the luxurious Rose Rayhaan by Rotana, as the tallest building solely used as a hotel.

Both skyscrapers are located in Dubai and provide their guests with an impressive view of the world's tallest building, Burj Khalifa.

The Makkah Clock Royal Tower might be the world's second-tallest building, but its Fairmont Hotel only occupies the lower two-thirds of the tower. The top third consists of an enormous clock tower whose face can be seen from as far as 17 km away.

A boom in skyscraper hotel construction is particularly evident in Asian cities - and the future will not see a reduction in the number of sky-high hotels opening there: three of the buildings in the list were only completed in 2012, and further hotels of superlative dimension are already in the starting blocks, among them the controversial Ryugyong Hotel in Pyongyang.

The 330 meter tall building, which has been under construction since 1986, will not now have the 3,000 rooms originally planned, but, in housing a Kempinski Hotel, will introduce the first western hotel chain to North Korea.
