Hotel staff at the Mandalay Bay who interacted with Las Vegas gunman Stephen Paddock more than 10 times during his stay didn't notice anything unusual, according to MGM Resorts International.

Paddock checked in to the hotel three days before he unleashed a torrent of bullets on a country music festival on Oct. 1, killing 58 people from the window of his 32nd-floor suite before he fatally shot himself.

The 64-year-old spoke to housekeeping on the phone and had room service delivered just hours before the massacre, a spokesperson for MGM Resorts International told the New York Daily News.

"There were numerous interactions with Stephen Paddock every day at the resort ... all of which were normal in nature," the spokesperson said. "As a result of these interactions, there was no need to conduct a welfare check."

In total, "Mandalay Bay staff, room service and housekeeping had contact with Paddock or entered his suite more than 10 times over the course of his stay," the spokesperson said.

Mandalay Bay had previously been criticized after a hotel worker who spoke to The New York Times in October said housekeepers had not cleaned Paddock's room for three days after he left a "Do Not Disturb" sign on his door.

While Disney and Hilton have changed the "Do Not Disturb" policies at their hotels, MGM Resort International has not revised its rules.

The company "stipulates a welfare check be performed after two consecutive days where a Do-Not-Disturb sign has been displayed on the door and the guest has not interacted in-person or by phone with housekeeping or other hotel staff over the same period."

"In addition, our staff reserves the right to enter the room if it is deemed appropriate to conduct a welfare check," the spokesperson added.
