My husband gave us a night at The Waldorf Towers for my birthday. Several scenes from my novel Lilac Girls take place there, so it was helpful to revisit the grand old hotel. One of the opening scenes takes place in The Peacock Lounge, adjacent to the lobby with its famous bronze clock:
Another takes place in the incredible Waldorf Grand Ballroom. 
Daughter Mary in the lovely lobby powder room.
I’d taken the wonderful Waldorf tour before and got a behind-the-scenes look at the hotel and heard its fascinating history, but actually spending the night in the Towers where Wallis Simpson kept apartments was a thrill and good research to boot.
