You can enter it directly in the ‘PROMOTIONS’ section that you will find during the booking process. Just fill in your personal information, open the ‘PROMOTIONS’ section and enter the promotional code.
Once you have filled in the field and clicked outside of it, the code will automatically be validated. If it is correct, you will see the amount be automatically deducted from the final price. Take a look at the purchase summary on the side to make sure that everything is correct and that the discount has been applied correctly.
Please note that discounts apply only to the amount payable at the hotel, not to the total amount of the reservation.
