The replies are exactly what I thought, and have been doing for many years, we are staying for 17 days and have an overlap, and need to move to let other people in, so although we are booked and paying for 14 nights, we can only stay for 13, then move to another apartment for 5 nights, which again they want to charge for 6, which means we would be paying 2 nights extra for the holiday, thanks for your replies,
