Grouped Scheduled Services For group courses (sessions with multiple students), a minimum of 72 hours’ notice is required for cancellations or rescheduling. Use your online account to cancel, available 24/7. Cancellations via phone, email, SMS, or voicemail are processed on the next business day. If this occurs within 24 hours of the course, you will forfeit your fee. To avoid this, cancel or reschedule with at least 72 hours’ notice via your online account. Group courses may be rescheduled as often as needed, as long as the 72-hour notice requirement is met.
