Belfast International is £3.00 per hour or £7 for a whole day which I thought was quite good. They do £20 a week in Long Stay.
Belfast City cost £4 for just over one hour and I had to stay there 10 hours one day which cost near £30!!!
Dublin I always found was good value, if you could find the paying machine!!!
Renfrew, – how much did they charge when you were there as its less than €5 (£3.33) for a Large Meal and Supersize being €5.20 (£3.47)
