Generally, Sand Dollar operates on a year-round, flat-rate tuition model. Tuition is due the first of each month and can be paid via credit card or bank transfer. Failed or late payments may result in additional service fees. In specific circumstances, one-off or drop-in lessons may be scheduled, provided that full payment is remitted before the first lesson. There are no refunds or exchanges available with any lesson package or drop-in lesson. Frequent late payments may result in termination of lesson contract. If, at any time, you are dissatisfied with services rendered, please reach out to Sarah or Christin.
