Each booking on holidayheroes is a combination of a flight reservation and a hotel reservation. The conditions for changes are the ones displayed on the website at the time of booking and also listed in the confirmation E-Mail you received after completing the booking.
Since this is a single booking, that includes flight and hotel, it is important to note that changing the flight date also requires a change in the hotel stay dates according to the conditions of the hotel reservation. A hotel-only stay is not possible.
If you decide to change the date, please contact us here.
