No.
It took 13 minutes for them to get to the shooters door.
He shot a Hotel security guy through the door, and probably committed suicide at that point, because the shootings outside the hotel stopped.
The SWAT team blew in the door an hour later. It likely took so long, because the shooter had stopped shooting, so they knew they could take the time to get it right.

I believe the shooting lasted about 5 to 10 minutes.
It was almost 2 hours before police entered the room.
Picture of dead Stephen Paddock showed blood had congealed. He had been dead for a while.
Why did one shooter, a 64 year old retired accountant with no experience in shooting, take 24 guns and an enormous amount of ammunition up to the room? Why did he modify the rifles? Why did no one in the hotel including cleaning service and maids notice the many guns?
Paddock also supposedly set up a tripod and platform for one of his rifles. He also set up cameras and linked them to his personal computer in the room.
Why did Paddock break two windows on separate sides of the suite? If he was the only shooter one window would be enough. Authorities said several weapons were fired. Why did he switch weapons?
Original reports said multiple shooters were involved.
No motive whatsoever. ISIS claims killer was a soldier of the Islamic State.
Many unanswered questions.
