...can you dance with another user? I'm just wondering because it doesn't say anything under "You have invited [insert username here] to a dance!" like it is with kisses.

You can always click the dance link again, and it'll show you how much time you have to wait. The time varies for each dance.

Your feet need a rest! You have You have 0 hours 5 minutes and 56 seconds before you can request to dance again.

Typically it's a ten minute wait.

Yeah, it's usually 4-10 minutes, until you can dance again. c;
