The Plaza: New York's Grand Hotel

Cameras focus on one of the Big Apple's most prestigious hostelries, which was built in 1907 and remains one of the most expensive hotels in the city's history, costing the equivalent of half a billion dollars to build. It had all the mod cons, including 17,000 electric lights and an air-conditioned room especially for ladies' fur coats. Today, there are 102 luxury suites, which can set guests back up to £30,000 a night.
