I have two trips reserved, one this year and one in March. We have decided to do the DDP for both and used the calculator to decide whether it would be a good deal based on our reservations. This morning when I put in our dates, the calculator kept adding the number of days rather than nights to determine the number of meals. For example, our first stay is five days , four nights. There is no way we could use a extra days worth of meals due to flight times. Is this a glitch in the calculator?
