I am planning to travel from Victoria Coach Station in London to Edinburgh Waverley or Bus Station by overnight coach which takes around 9 hours. I have found two booking options FlixBus and Trainline.
I am trying to decide which one is better in terms of reliability punctuality comfort and overall safety. The Trainline option is noticeably cheaper but I do not want to compromise on safety or comfort for an overnight journey.
Has anyone compared these two services on this route and which would you recommend?
