Redeemable items are an optional feature that can be used in tandem with the tickets. Redeemable items could by a physical item (ex: gloves) or an additional experience the guest gets with their ticket (ex: rock wall climb). It is important to note that these redeemable items aren't tied to any kind of inventory and redeeming the ticket or pass they are associated with does not automatically redeem the redeemable item as well.
