1st trip to Ireland, any ideas, tips?

Hi,
I heard the "unforgettable fire" show in nyc sat nite was a blast, I
wish I could
have been there.

My girlfriend and I are going to our first trip to Ireland on Oct 16 and
wanted
to see if anyone could offer any tips,suggestions,web sites, personal
stories etc
on how we make our trip more enjoyable and since we are only spending 2
days
in dublin(making our way towards shannon airport), any suggestions on
U2-related sites.

Private e-mail is fine, as I dont want to clutter up the list.

Thanks very much,
George
