The discount is based on the third highest current price of the property for rooms with the same booking conditions in a 20-day window around your check-in date (10 days before and 10 days after check-in date; if less than 10 days are between today and the check-in date, we will use the corresponding number of days after the check-in date to result in a 20-day total). To ensure we are making a fair comparison, we always use the same reservation conditions (meal plan, cancellation policy and room type). This means that you get the same room for a lower price compared to other check-in dates at the same time of year.
