How does one become a good dancer?

Question:

How does one become a good dancer?

I'd like to learn how to dance, especially to swing and hip hop. Most of the classes I've found are centered on choreography, but I just wanna be good enough to enjoy myself at a club and not look like a fool. Any suggestions?
P.S. Yes, I have rhythm, so that's not a problem.
