Not exactly sure what you are looking to do, but for clubs, XS (Encore) is the best club in my opinion, although Marquee (Cosmpolitan) is very popular right now because it is the newest. Surrender (Encore) is also a good spot, although it depends on the weather since most of the space is outside in the pool area. If you are looking for bottle service and a table, you will need to get in touch with a host to make a reservation. You can contact the appropriate hotel concierge and they can help put you in touch with one. If you do not make a table reservation, try to get in line EARLY, as in before 10pm. It helps to bring girls with you.
