When James Bond is in New York City as Peter Franks (but traveling as James Bond, if that makes sense) in Diamonds Are Forever, he is booked into the Astor Hotel by the diamond smuggling organization he is working for.
Because of that, unlike in Live and Let Die at the St Regis, Bond does not get the top suite in the hotel, just a standard room. He spends most of a weekend there, including most of the day on Saturday when he sat in his air-conditioned room, avoiding the heat and composing his report.
Tiffany Case is also staying at the Astor, and as Bond leaves her at her door Friday night, she suddenly kisses him and then pushes him away.
In the short story 007 in New York, Bond also stays at the Astor.
The Astor. It was as good as another, and Bond liked the Times Square jungle – the hideous souvenir shops, the sharp clothiers, the giant feedomats, the hypnotic neon signs, one of which said BOND in letters a mile high. Here was the guts of New York, the living entrails.
The Astor was located in what is now Times Square in Manhattan. Built in 1904, it played a large role in making Times Square the center of New York. The hotel operated until 1967 , it was destroyed in 1968 and replaced with a 54 story office building – One Astor Plaza.
