I was staying at the Mirage 6 months ago. Around 3 to 5 pm, there must be 10-20 casino girls working inside the casino. To avoid being obvious, they move around quite a bit. The best way to get them is to give them eye contact when they are walking. $$ will be plenty at that hour. I believe you can probably find better looking ones at Bellagio, MGM, Hard Rock or Rio.
