I have been three times now. My wife and I visited Dublin for the first time back in 2002 and ever since then we're hooked. We made another trip over in 2006 and if anything, it was even better than our first trip. Meeting the people, seeing the sights, there's something about Ireland that just makes me feel so happy.
Our last trip was a really special one for my wife in particular because we headed north to see the locations they used for Game of Thrones. She's a huge fan of the show and insisted we go and visit. So we planned our itinerary and off we went. I would totally recommend any fan of the show do this though. Some of the locations are breathtaking and my wife was so happy just to be there.
Sitting here and writing this is starting to make me think though. Might be time for another adventure in Ireland. :-)
