Hi,
You will be spoiled for choice in that part of Ireland, you are however spending a lot of time in a relatively small part of the country. For coastal shots make sure to include the Cliffs of Moher. The Landscape in western Galway (Connemara) is excellent, Killary Harbour and Leenane are another must see.
But don't forget the other side of Ireland (East/Southeast) and also the South west.
I run photographic tours of Ireland and have a tour running from 12th-18th August, where we will be around the East and Southeast (Seascapes, Landscapes, lakes, mountains, ruins etc.) If you PM me I can work with you to see if we can work something out for you (as you are a fellow APUGer) if you wanted to join the tour.
I have actually posted some information about us on APUG, see thread (there was a url link here which no longer exists)
Hope this helps and don't hesitate to PM me.
David
