Dublin isn't cheap. But the flat, compact Irish capital is exceptionally walkable, with a wide range of free attractions easily reached on foot from any downtown hotel. Live music might cost no more than the pint that's probably in your hand. And exhilarating seaside hikes with a salty breeze are just a 15-minute train trip away. This year, for anyone sporting an Irish surname, Ireland is offering an eclectic and ever-growing list of family-clan events called The Gathering, http://www.thegatheringireland.com/, a yearlong effort by this nation of 4.6 million to reconnect with the tens of millions of O'Somebodys worldwide. Even if your name sounds more like Pogatchnik, Ireland's tourism industry is still hoping you'll leave a good part of your wallet here.
