When booking the bus it is unclear that a time will be assigned to you and you cannot change this. This is incredibly frustrating. I booked a return trip however decided to find a different way home as the time allocated to me was awkward and difficult to work around. I wish this was clearer when booking. Furthermore, the bus collecting us to bring us to the airport was over ten minutes late. While I understand these things are often inevitable, I feel like this would also be helped by allowing people to choose their own bus times. This added an element of stress to my journey, which would have been easily avoided if I could have simply selected an earlier bus time myself. Overall would not use or recommend service to anybody.
