However, now I’ve noticed something. If you use the booking form on this page:
when you select the dates, it calculates 15% of the amount I should pay.
You can verify that the boat costs €160.00, but after the 21st, it costs €180.00. Now, let me explain the issue:
If you try to select two dates, such as from July 27th to July 28th, you can see that it calculates €54.00, which is 180 * 15/100 = 27 * 2 = 54. So that’s correct.
However, if I try to select just one day, for example, from July 27th to July 27th, you can see that it no longer calculates €27.00, but rather €24.00, which is 15% of €160.00 instead of €180.00. Meanwhile, the selected date range from the 27th to the 27th has a price of €180.00.
