Yeah, Cathy Y. is not far off. If you are a group of single girls, you should have no problem getting in and free. The trouble starts once you are in and some really dirty guys are all up in it. But how you choose to deal with that situation is up to you. Some girls like eurotrash and Saudi kings in Vegas on vacation. No problem, you will love this place.
It is truly ginormous. (OMG, that passed spellcheck, is ginormous really a word?) The atmosphere was unique and fun and I appreciated all the different music areas. While the drinks are pretty good at the bar (pricey of course), avoid the shot waitresses that come around. Those things are straight pucker and only 8% alcohol.
Bottom line, if you are a group of single girls. You can just show up (getting a VIP pass ahead of time is a good idea) and have a great night dancing and bouncing around to all the different clubs. However, if you are with a group including guys, it might be worth getting a table. Quite a hefty price tag but some of the tables in the place are in stellar locations for dancing and watching all the action. Others are more removed and not worth whatever they cost. The Vegas club scene is not my favorite way to party the night away, but it definitely is for some people. Spend some serious money and have some serious fun.
