Cork is a nice place man, you'll have fun... just get used to the fact that they say "like" a lot... you know what I mean like? That is just the way they are like! Like it or not like!
Shame it is only March... there are some great hidden beaches around that part of the country that can be Caribbean like on a hot summers day. I go there a lot with my friends! You can have a small white sand beach with crystal waters all to yourself.
See if you or any of your mates are up for a challenge... my friends Dad downed 38 pints of Guinness at his daughters wedding last November. Most talented drinker I have ever seen! He was still standing too.
