Registered series on the schedule are filled on a first come basis, drop-in options for joining a particular series will only be available if space allows and on the first day of the series. For example; once a series begins and there is two open spots, students will have an option to book one of the free spots via the drop-in price.
If you book for the full series, there are no refunds or credits should you not be able to make it to class (much like other registered classes i.e.: swimming lessons)
Classes may be purchased online or in-studio.
