what would you do if....

You were offered to take dancing lessons at a cheaper price.. with a group of people.. five or so months before your wedding?

Do you think we should wait?? Fh's sister is getting married in July and asked us to take dancing lessons. We don't know what to do b/c they will be over in May or June. Is it worth it? or should we wait until a little more before the wedding???

TIA
