Check out the Irish pages poacher, give you a sense of what is achievable over there. Counties, Kerry, Cork and Donegal produce for us on a consistent basis as does the port of Kilmore Quay. Kilmore would be the most convenient for you guys if you don't want to travel too far, dead easy to get to, drive to Pembroke Dock or Fishguard, hop on ferry, couple of hours over the Irish Sea, quick 20 minute drive to Kilmore and you're there! Recommend you stay in Kimore, the Quay House, can't really beat it, best pub (pint and food) Kehoes (as people will recall I mention this place often

) Couple of lads from this forum went last year a week before we did, can't remember who it was though! Plenty of places to fish both off shore and shore and you can mostly get out with the weather. But as with everywhere, weather is always a pain! Plenty of charter boats too.
If you want anymore info, I can dig out some e-mail addys, phone numbers out for you.
