Palms owner George Maloof was arrested on drunken driving charges Saturday night, Las Vegas police said.
Maloof also was cited for driving without a valid license, no proof of insurance, failing to properly make a left turn and speeding.
Maloof, 46, told Review-Journal columnist Norm Clarke that his biggest regret is "that I always have a driver. I feel horrible. I wish I had listened to my assistant."
He said he had just attended a wedding at The Mirage and his assistant offered to drive.
"Four beers, man. I didn't think I was anywhere near intoxicated," he said.
He was pulled over while driving into Spanish Trail, where he lives. His blood-alcohol level registered an 0.08 percent and was he was arrested at 11:36 p.m.
He was held overnight at the Clark County Detention Center and released after eight hours.
