When taking lessons with us you need to reserve your spot by making a one hour deposit. This is refundable should there be no wind. It is not refundable if you are a no show or cancel.  You may reschedule your lesson giving 3 days notice.  We have to enforce this policy due to other students wanting lessons at weekends. When you book, your instructor is made available to you for that day.  Other students in line have been told that there is no availability for that day and are likely to have other plans/or not in the Hamptons that weekend.
