While it’s never advisable to exchange your currency at a hotel or airport, there are places in Dublin where you can do this if absolutely necessary. Dublin’s international airport is served by foreign exchange kiosks placed in various locations in and around terminals 1 and 2. You can find the exact locations and opening hours for each kiosk here. You may also find a foreign exchange kiosk in the reception area at your hotel.
Exchanging currency at the airport or hotel is convenient, but that convenience comes at a price. Because they’re often a last resort, kiosks at hotels and airports offer unfavourable exchange rates and higher fees, thus making it very unlikely you’ll get a fair deal.
