I plan to travel to Ireland for a 12 day country tour that starts in Dublin, and includes Belfast.?

The Republic of Ireland use Euros (€), Northern Ireland use The UK currency Pound Sterling (£).

$1 will get you about 70-80 cent, not even a full euro. Look up the currency exchange before you go, I'd recommend you do the transfer in the USA as im sure you'll be ripped off here, but yes, you can do a currency exchange over here just contact the bank in advance, all though I wouldn't recommend doing it.

Euros is indeed the currency of The Republic of Ireland. Northern Ireland is park of the UK and uses Great British Pounds.

You can exchange Dollars for Euros in the Airport but the rate isn't usually very favourable, you're best off getting some Euros and Pounds before you leave. You'll be able to get cash out of ATMs, you're best off telling your bank first though, as they may cancel you're card thinking someones stolen it.

Tips for prompt service? Be nice, polite etc. Certainly don't click your fingers, yell "Hey, Over Here!", or passively aggressively declare "Is nobody working here!?".

As Northern Ireland is part of the United Kingdom, it uses the currency of the UK, which is the pound sterling.

You can get whatever currencies you need from ATMs, but you should inform your bank before you go, and tell them exactly where you are going, so they don't block your card. I would advise bringing a Visa or MasterCard credit card for emergencies and big spends, and getting a couple of hundred Euro in cash to bring with you so you can easily sort out your transport at the other side.

All service is as prompt as it needs to be. Most people who work in restaurants and bars are Eastern European anyway. Still, be nice. Everyone is working to keep a roof over their heads and food on their tables.

Euro for everywhere in the Republic and pound sterling for Northern Ireland, though most border areas will take the euro, however the exchange rate would not be good.

Sure you can get euro and sterling at atm's.

If use EUROS in the NORTH are wasting your money....DO NOT overtip as seen as a soft touch if do.....10% is VERY generous....

EURO in NI? Why when a part of the UK....?

Just do what you would normally do, be friendly, and you will receive friendship back.....Like any others
