No, you cannot pay for several reservations with one payment.
Each payment is linked to a specific reservation and is not automatically linked to multiple orders. You have to make one payment per order, otherwise you run the risk of having your orders cancelled.
If you have made an incorrect payment and the status of your tickets has not been updated in your account on our website within three days, please contact the Customer Experience Center. Please do provide us with the proof of payment so that we can look up your payment more easily.
