If you have booked with a tour operator, you will need to contact them as this is a term of our contract agreement.
For bookings made directly or on our website, please create a ticket with the new dates and we will inform you if it would be possible and if there is any increase or decrease in price. We do not charge a fee for modifications but if rate has increased or decreased this will be quoted to you accordingly, then we shall be awaiting your confirmation to proceed to make the modifications.
