You can purchase multiple blocks of 20 at a time — just use the drop-down menu. For example: choose 1 from the drop-down menu for one block of 20 guest credits (20 total for $85), choose 2 from the drop-down menu, for 2 blocks of guest credits (40 total for $170), etc. They are good for the current season only.
Bring a friend, and have more fun!!
See You at the Pool!!
