If you need to make any changes to your booking, the person who made the booking must notify us in writing via email or post, as soon as possible. We will do our utmost to make these changes but we cannot guarantee this. Certain travel arrangements (e.g. low cost flights) cannot be changed after a reservation has been made and any alteration request may incur a 100% cancellation charge.  Amendment fees will apply, we will provide full details of any additional costs before making a change. Please note: if you do not receive acknowledgement of your requested change within 24 hours of submission, you must contact us by phone or re-submit your request – it is essential that you receive an acknowledgement from us, otherwise your change will not be guaranteed.
