From the Niagara Falls Review:
Marilyn Monroe slept here.
It’s Room 801 inside the Crowne Plaza Hotel in Niagara Falls and if you play your cards right, you can sleep there, too.
It’s on the eighth floor, right at the end of the hall, on the left side.
“It’s more than just the room, it’s the entire hotel because this is where she stayed when they were filming the movie Niagara,” said Joseph Legace, general manager of the Crowne Plaza Hotel.
