"Tiger's was one table that was always to be filled with hot party girls. He's obsessed with women, and he loves being catered to," the source said. "Keep in mind, he doesn't hook up with everyone, only the ones who recreate dating in the 'real world' -- in one night. He chases tail like a frat brother -- making them cocktails, asking for their phone numbers. All of his friends help."
When a celebrity requests party favors -- like cocaine, marijuana, ecstasy, or Ambien, one of the drugs Woods reportedly did with his mistresses -- clubs bend over backwards to make sure the star's substance of choice is waiting when they're done partying.
"Drugs may not be done in the nightclub because it's risky, it's an open area, but [stars] can get it delivered to their hotel suite," Trotter said.
But the partying often keeps on going -- much longer than 4 a.m., when most Vegas nightclubs shut down. After-hours spots like Drai's, which was reportedly one of the favorite haunts of Rachel Uchitel, the nightlife promoter first linked to Woods, cater to the club workers and their celebrity friends who want to party until long after the sun comes up. This reporter once left Drai's at 8 a.m., with the dance floor still packed and the drinks still flowing. And after the club, the party often carries on in the client's room.
"Those girls after-party until 7 or 10 a.m. the next morning, hook up with VIP clients, and then hit the pool scene the next day," ABCNews.com's source versed in Vegas nightlife said. "The change comes naturally. The people who work in the clubs work all the time, so often they end up dong a lot of blow to stay energized."
For Woods and like-minded stars who demand it, nightclubs make sure Vegas truly lives up to its reputation as the world's preeminent adult playground.
"Nowhere else in the U.S. has everything Vegas has within such a small amount of mileage. Within the span of 4 miles, any VIP can come here and get the most lavish suits and pools and restaurants and nightclubs in the world, and it's all within 10 minutes of each other," Trotter said. "It's a win for everyone. The clubs get tons of publicity. The celeb gets everything comped plus all this service. They have the time of their life."
