Princess Diana, that heralded the Upper East Side hotel as a favorite among British royals. Diana stayed for the first time at the Carlyle in 1995, when she made the trip across the Atlantic for the United Cerebral Palsy’s annual dinner.

This was a significant night in Diana’s charitable career — she rubbed shoulders with American political heavyweights Henry Kissinger and Colin Powell, she accepted an award for her humanitarian
activities and delivered a stirring call to action on behalf of the needy.

She revisited the hotel in June 1997, the year that 79 of her most iconic gowns went up for auction at Christie’s.

So it seems Prince William has chosen to follow in his mother’s footsteps, electing to stay in the hotel that Diana loved. The young couple will be put up in one of the The Carlyle’s most glamorous rooms – a suite with a view overlooking Central Park.

Their seven-strong entourage will also be staying at the hotel, with at least one of them — Kate’s hairdresser Amanda Cook Tucker — being paid for privately by Kate and William.

As they arrived at the hotel last night, Kate and William were greeted in the lobby by a welcoming party consisting of concierge and hotel staff. In place of the stars and stripes that usually fly proudly over the  entrance, The Carlyle instead raised the Union Jack in honor of the royal guests.
