You are better of flying to Dublin, the roads are pretty crap in Ireland!!!
What a place to stay though!!! I didn't know that existed in Ireland!!! Must make mental note to go there!!!! In wicklow you have a better chance of sun than most other places in Ireland but don't bet on it!! I will try to get back for around that time (on the wedding stuff excuse!) but have to see what finances are like first! Let me know if and when you may be in Cork!
While there you should check out a famous pub called Johnnie foxs
http://www.johnniefoxs.com/
It says that it is in the dublin mountains but I was always lead to believe that it is in the Wicklow mountains!! Either way it shouldn't be too far from you!
I will try to find other places and bars of interest for you!!!
Would you like some Irish phrases?? not that you will need them of course!
