Apologies, currently our website does not handle booking a return with slightly different waypoints well.
The quickest way to achieve this is to get a quote for an identical waypoint return journey and complete the booking form through to the basket page (with the T&C agreement checkbox).
Once here you can amend the waypoints on any of the journeys in your basket by clicking the small icon next to each waypoint, this should allow you to book with different waypoints.
If you have any problems with this please contact our customer services team who will be able to assist.
