Hi Anthony,
It's great that you are planning your trip to Ireland around a few bases, it will certainly be more enjoyable and relaxing to travel that way.
In addition to
Dublin (which also has
coastal villages nearby and
day trip options), I would suggest picking bases away from each other in both Ireland's Ancient East and the Wild Atlantic Way,
Kilkenny,
Cork,
Killarney,
Limerick, and
Galway would be good choices, as they are far enough from each other and offer many day trip options.
These cities are also quite enjoyable to visit as well. Our
trip ideas page might also inspire you to plan day trips out of your chosen bases, such as the
Ring of Kerry, this
West Cork trip idea, or day trips out of
Galway and
Connemara.
I hope this helps - let me know if you have any other questions.
