When I went to Ireland, I was living in NYC, and I grew up in LA. So the city-ness of it didn't bother me. I just didn't like it as a city. I much preferred my time outside of it.
The Cliffs of Moher are absolutely amazing. I had a crazy bus driver get me up there, but it was just stunning.
The Ring of Kerry is cool. If you take a tour bus around it, you do need to keep a sense of humour. I was lucky enough to have made friends with some others from the same hostel and we had a good laugh about all the 'historic' stops we made.
Galway was cool. (Weston-super-Mare actually reminds me a lot of Galway, which might be part of why I like it here.) I was there during Race Week, so it was really expensive, very packed, but tons of fun.
I loved Cork, and actually thought about going to grad school there. The double decker tour bus that goes out to Blarney was amusing. (I really love cheesy tour bus things that go for an hour or two. They crack me up.) I refused to pay to enter Blarney Castle, though. It was extortionate. (All of Ireland's museums and historic sites are (or at least were) free to enter.)
Now I really want to go back for a longer period of time....
