Ive been to Vegas before, most of those clubs you mentioned arent exactly easy to get into, but just about anywhere in Vegas is fun for me. I mean just walking around the strip you see all kinds of chicks, and going into the diff hotel/casinos seeing all the cool stuff they have lots of chicks there.
Tip : Make friends with lots of guys you see in a casino, or make friends with some male bartenders, trust me, most guys come for a party, you become friendly with lots of them Im sure you will find one that will invite you to some party or they know of another one. With bartenders male or female, you can be sure plenty of people come to the bar talking about a party going down, so if you warm up to them you may get some good party places from them.
Bring a camera, who knows you can take pics of the cool hotels and lots of chicks go to have fun so you may meet lots of chicks who wont mind posing for a pic with ya, even after a couple min of knowin ya.
