Game of 2 halves... 1st. Journey from Dublin Airport to Dublin centre, bus very busy and not clear whether we would get on but driver very helpful, did a headcount, said he could fit us on and we bought tickets at the ticket booth - perfect! 2nd. Return journey back to airport. Thought would get ahead of the game and went online late at night to book ticket for next morning. Went through entire process (as Guest) only to find after payment that must "PRINT OUT TICKET" for journey. Not possible as in a hotel late at night so why not mention that AT THE BEGINNING not the end of the online sale process? Better still, how about move in the 21st Century and cater for digital bookings/tickets? Will be having an interesting discussion with the driver in the morning....
