If you have an Argentine passport (or another Latin American passport), you can enter Ireland as a tourist without a visa for up to 90 days. You only need a valid passport and proof of your tourist status (return ticket, reservations, etc.).

In 2 or 3 days, you can see the highlights of Dublin, including major attractions, some pubs, and even take a day trip. If you only have one day, you can also make the most of it with a walking tour.

The euro (€) is used in Ireland. It's best to bring some cash from your country or exchange it at exchange offices in central Dublin. You can also pay for almost everything by card or using apps like Revolut.

It's not mandatory, but it's customary to leave a tip of 10% if the service was good. It's not common in pubs, unless you're at a table with personalized service.

There are several options: the Aircoach and the Dublin Express are comfortable buses with Wi-Fi that drop you off in the city center. There are also cheaper public buses (16, 41), but they take longer. Taxis cost more than €30.

If you're only going to be in Dublin, it's not necessary. But if you want to explore other areas like the Cliffs of Moher or the Wild Atlantic Way, it might be worth renting one. Remember that driving is on the left.

At the airport or downtown, you'll find Vodafone, Three, and Eir stores. There are also tourist options like Airalo (eSIMs) or SIM cards with unlimited data.
