I don't know about the ones who never sign up again but I know a ton of families at our gym "quit" for the Holiday's mainly because our gym closes for half the month of December and charges a full months tuition and people feel like they are getting ripped off, and in fairness I can see their point, although I have never done so myself. One way to combat that issue that I have seen is paying by semester and if the family pays the entire semester up front they get a small discount (5%) and if not it is due in installments but the child is enrolled for the entire semester and tuition is not refunded or pro rated. I have seen a lot of gyms actually explain that the Holiday break has been factored into the tuition or that it is made up in the months that have 5 weeks. I don't know if it is true or not honestly but sometimes people just need a reason.
