They probably only have room for so many students. Try again or get on a waiting list. We take adult tap dance. AARP had an article on it a few years ago and their old people expert said that it was good for balance and coordination. My wife and I started last year about this time. Each session is six weeks and it is always crowded at first. People start dropping out after the second lesson. There is always a waiting list for our class, but once in, current students get priority. We used to go to Puerto Rico a couple of times a year and we always came back mid session. Even though the sessions fill up, they let us come in mid session because so many people drop out. I would say not to give up on it. You will eventually get in.
