Ireland Itinerary

My wife and I are putting the finishing touches on our itinerary for our trip next week. I believe we are doing a "green blur" tour. We don't have any dinner or night life plans as of yet. Any comments, criticism or advice is welcome.

Day 1
-Arrive in Dublin. Transfer to our hotel, The Westin.
-Site seeing and lunch
-Viking Splash Tour
-Dinner, early night

Day 2
-Take bus to Powerscourt
-Back to hotel after lunch. Finish seeing what we can of Dublin.

Day 3
-Early start. Pick up Car. Drive to Glendalough, spend a couple of hours?
-On to Avoca. Lunch and touring the Mill. Spend some time in the town at Fitzgerald's, the church, etc. (Wife is a Ballykissangel fan)
-Drive to Wexford.

Day 4
-Depart hotel. Pickup items for packed lunch.
-Drive to the Rock of Cashel
-On to Blarney Castle
-On to Killarney. Check into B&B
(Is this itinerary too ambitious? Originally we were going to stop in Waterford and tour the crystal factory before heading on to Killarney but decided on these stops instead. We are very open to suggestions)

Day 5
-Enjoy Killarney National Park

Day 6
-Depart Killarney for the Cliffs of Moher
-spend about 90 minutes at Cliffs of Moher?
-Lunch in Doolin
-Drive to Ashford Castle

Day 7
-Daytime open. Grand finale dinner someplace nice?

Day 8
-depart hotel at 5:00 a.m., drive to Shannon airport, drop off rental, flight departs 9:15 a.m.

I appreciate any comments or suggestions.
