What is a good nightclub in Orlando, FL?

I am from Los Angeles, Ca and my sisters and I are going to Orlando in July! We already have a couple of things planned but we really want to experience the night life out there! So we would like to go to a good nightclub with good music (top 40 and hip hop, preferably) somewhere that is nice and not a lot of drama and hassle to get into like at some clubs...where can we go?
