Windy, my suggestion would be for you to enter the bus station from the ring road and go up to the back and go around the shop fronts and come down behind the buses in the first bus parking and go to the end and you should be able to get parking there. The mistake that I made was I turned across the front of Terminal 2 and there was no parking available there but there was empty parking in the next row but you can only access it by going past the turn across the front of the terminal. The big problem is that if you do what I did you cannot reverse back to go down to the next row because you could end up with a bus going over the top of you because it is their exit road.
