You can use Purrk Passes as walk-ins any time. Just present the card when asked for payment.
If you’d like to make an online reservation with your Purrk Pass, enter the reservation code on the bottom of the card as a PROMO code. You MUST bring the card with you and surrender it at check in in order for admission to be covered. If you don’t bring the card, you must pay admission until you can present the card.
