Check out my thread in the UK/Ireland forum under FT Travel (might have to dig back a couple months). I went in May and it was awesome! Dublin is a great city and we spent a good amount of time out on the West coast in Killarney. B&B's are definitely the way to go and inexpensive as well... if you hit a great one, make a note of it for next time. Good B&B's are valuable contacts! (Drop me a line if you need a recommendation for Killarney. We stayed at a good one in Dublin too -- but it was just a bit out of the way. If you don't mind that, I can recommend it as well.)

The restaurants are great, and the people are generally warm and friendly! The scenery is literally "breath-taking." Ireland is a stunning place. Enjoy it!
