If you've got a promo code, you'll be able to apply it when you get to the payment screen during the booking process. Enter the code in the box and click Validate Code - you'll then notice the amount has been taken off the holiday price. If you have any problems entering your promo code, please contact us and we'll do our best to help. Unfortunately, if you've already booked your holiday, we can't add any codes afterwards. Promo codes can only be used when you make a new booking.
