Booking and journey itself was sound. However i made an error when selecting pick up location. Called up in advance to request amending it as there wasnt a difference in price. Was told via phone that only date or time of booking could be changed but not locations so he advised to either take a chance and get on at the different stop but as it wasnt where I booked I'd be at risk of being marked as a no show or else i should rebook entirely and request a refund. This seemed like it would be as much hassle for aircoach as it was for me so before booking i emailed the next day and sure enough the girl was able to amend and resend a new confirmation, very straightforward.
