Hi heading to the above hotel tomorrow and caught for time in the morning so cant depart as early as I would wish and need to be checked in 4.30 so as I can head over to Croke Park. I dont know whether to take car ( no sat nav ) or get the train ( how far is from Hueston ) and unfortunately flying isnt an option. If I was coming from Cork what exit should I take on the M50. Any advice ?
