Read that the Bank of Ireland has removed it's ATM's from the airport. Per Rick's guide books, he says to get Euros at the airport. Are the remaining ATM's good to use? Concerned about excess fees and transaction charges. Thanks!!
If it is bank owned ATM I would be OK. If it is one of the exchange's ATM then read the screens carefully. Nearly all countries require disclosure of fees.. Most of your fees will be set by your local bank and the exchange rate is determined by the network provider -- generally VISA or Mastercard. There could be a fee to use that ATM and it will be disclosed on one of the screen and you can cancel. Generally that fee is a couple of Euro and worth it for the convenience.
While the least expensive way to get local currency is from an ATM at your destination, it's always a good idea, in my opinion, to have some local currency in hand when you land. Getting two or three hundred of the local currency from your local bank will cost a little more, but it eliminates the hassle of trying to find a machine, the stress of hoping it works (they do occasionally malfunction), and doing it all while somewhat jet lagged. The small extra amount it cost to have money in hand when arriving is money well spent, and the extra cost relative to the overall cost of the trip is really not that much.
Regardless, be sure to notify your bank and credit card companies that you will be traveling. Otherwise they may see a foreign transaction, suspect fraud, and shut down access to your cards.
