If your 21 go to Church Street it is in Downtown Orlando, it is basically a strip with a lot of clubs and bars.... Lot's of Chicks

I don't know about going in the middle of December because it is very cold over here...or at least it is for Floridians..
Also hit up Gators near UCF (Univ. Central FL) it is pretty packed on Fri nights...but i don't know about this time of the year since schools out.
