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.
Members can pay this fee annually, if they have childcare providers who need to be able to access the pool (with family members). You must send the name/birthdate/cell number of your childcare provider to email@example.com after you submit your payment.
You may choose to purchase guest credits in a block of 10 ($45 each block of 10). They are good for the current season.
