All cards are validated for 60 days except for the mat which is 60 days. The validation will take effect the first time it is used. Persons living in the same household may use the same card. If an instructor cancels a class that is on the schedule due to personal reasons then 5 extra days will be added to the card. Clients must register by 3:00 pm the day before each class. If only one client has signed up for the class, the client will be called and ask to reschedule when there is another person signed. There need to be at least 2 people to hold an equipment class or 3 people to hold a mat class or have the option of paying double and have a private class. Drop ins are always welcome, but if no one has signed up or the class has been changed due to only one person initially signing up the classes are cancelled.
