Watch World's Greatest Hotels

We arrive in style at one of Hong Kong's most historic hotels. In a city teaming with more billionaires than almost any other, flying into the Peninsula by chopper is the norm, with not one but two rooftop helipads.

The Plaza Hotel in Manhattan is a celebrity in its own right, appearing in dozens of iconic movies from "Home Alone 2" to Hitchcock's "North by Northwest."

We're heading to the city of love to check into one of Paris's chicest hotels: Four Seasons Hotel George V, one of only 31 in to belong to an exclusive group of Palace hotels.

We step inside the front doors of London's oldest hotel: Brown's. Sitting pretty in the heart of trendy Mayfair, Brown's is a true bastion of Britishness and a luxury landmark.

We immerse ourselves in the underwater world of Hotel Atlantis in Dubai. Perched on top of a giant, man-made palm tree-shaped island in the Arabian Gulf, this hotel made the biggest global splash EVER when it opened just twelve years ago.

We're taking a walk up the red carpet and heading inside a hotel that's played host to Hollywood royalty for the last six decades: the Beverly Hilton.

We're heading to London to check in to a quintessentially English hotel with a naughty streak: Claridge's. Situated in the heart of swanky Mayfair, Claridge's has a well-earned reputation as being both a private retreat as well as the ultimate venue.

We're hitting the Las Vegas strip to check in to one of Sin City's most iconic hotels: The Bellagio. When it first opened in 1998, the Bellagio was the most expensive hotel ever built.
