See Pay My Balance.
If you have a credit in your account, you may use it to pay for programming when registering online. If the credit is in the current season (for example if you cancelled a week of summer camp and wanted to enroll in another week that same summer), it will automatically be applied to your cart when you are adding new sessions, so when you go to check out you will see the remaining balance. If you have credit remaining from a previous system, please contact the office so that we can transfer it into the current season. The above applies when you are using your account credit to pay for any program that uses our online registration system. You may also use your account credit for birthday parties, custom quests, and merchandise from our online store. To do so, please contact the office.
