I'm having some difficulty figuring out if there even is such a thing as a 1st class train ticket from Glasgow to Oban. I've studied the help menus at ScotRail and the timetables and the advance ticket sales. I'm especially interested in getting a first class ticket from GLQ to OBN because we might have about three hours to wait at Queen Station between airport bus and outbound train. A first class ticket would allow us the use of the Millenium Hotel lounge.
Is there a first class? And how does one go about buying an advance ticket?
