Upon confirmation of your booking, you will have been sent an email which includes the contact details of your designated transport operator. For any changes you may need to make to your booking, you should speak directly with the transport operator.
Bear in mind, changes made to a booking due to take place on the weekend or during peak times may potentially incur an additional charge from the designated transport operator, subject to vehicle availability. Please try to give plenty of notice! (The more notice you give to the taxi company about any changes, the greater the likelihood that your journey will run smoothly).
