Jim,
I've been there on a number of occasions over the years, last year was the most recent. The South is great. I would ride through Wales from yours to Pembroke, ferry to Rosslare and head for Cork, Limerick, Killarny, ring of Kerry and Dingle and then to Galway. (Check out the Sears Pub at the dockside!) Make sure you see the Moah Cliffs, granite at its best. The roads are okay, but rough around the 'Rings', not many cameras, but there are two on the road to Cork now. Lastly, go from Galway to Dublin, a great road (Check out Temple Bar) and then ferry back to Holyhead. A55 back across to hester and home.
I have some B & B phone numbers on that route if you want them?
