Take advantage of any special the studio might offer. Do not be afraid to shop around. Now here is your question checklist. Remember studios should not be afraid to tell you how much lessons are beyond the special. If they are, put up a red flag.
Most studios charge the same per lesson for singles and couples.
Now do yourself a favor and just enjoy and have fun. Now before you purchase a block or single lesson, do your personal checklist. Never be afraid to check out other studios. Be a smart shopper. I wish you success and enjoyment with your dancing.
