Payment Information

We accept cash, check, and credit card (American Express, Visa, Mastercard, and Discover) as payment for classes.

Cancellation Policy & Refunds

No class refunds will be made after the first class meeting, unless the City cancels the class. Requests for refunds for one or two-week workshops must be made prior to the first class meeting.

There will be a $15 fee charged (per class) for the processing of all requests for refunds. The refund charge shall be deducted from the total fee paid, and the balance will be returned. If the refund is $5 or less, a credit will be issued. The credit can be used for any recreation class. (Note: A $15 fee will be charged for returned checks. Refunds take approximately 4 to 6 weeks to process.)
