It's as easy to find an affordable hotel in Dublin as it is to come across a good foamy pint. Failte Ireland features a collection of two-night minibreaks, which include accommodations and breakfast for two people, starting at €75 per person (about $94 USD) at various local hotels and B&Bs. And you can find a helpful roundup of hotels for less than $150 per night on The New York Times' website. Moreover, Dublin is brimming with free, worthy attractions, including the National Museum of Ireland, the National Botanic Gardens, and the Irish Museum of Modern Art.
Getting to Dublin from the U.S. is quite affordable, too. International budget carrier Aer Lingus makes Dublin, its main gateway, a very inexpensive European hub to fly into. The carrier often features very competitive fare sales, especially during colder months. We've seen round-trip fares from the U.S. to Dublin drop below $500 in the low season and under $1,000 during the high season in summer.
