Itinerary advice

Wow! Are these mostly one night stays? Those are exhausting.

Although I have not been to Ireland yet (we leave in 2 weeks for 15 nights), I have done extensive research. I think you may have too much crammed in your itinerary and no time to just "experience Ireland" rather than rush from site... but I'll refrain from too much comment and see what the experts say.

It's great that you are including No. Ireland, too. We arrive into Belfast for 3 nights and travel clockwise to Connemara area and leave from Shannon. We made concessions: We are not seeing New Grange, Limerick, Tara, Blarney, Cork, and unfortunately we are only passing through Galway for a few hours on a travel day. I can elaborate more in a few weeks.

In my opinion, having spent 3 weeks there in May, you are packing to much in too little time. In fact, days 4 & 11/12 look impossible to me. We found that it took us longer to get from Point A to Point B than we expected and, of course, you will want to spend some time at each site-- not just drive past! For instance, when you do go to a site you will probably have to wait for the next scheduled tour, etc. It all takes more time than you might anticipate.

That said, you will have fun, especially if you give yourself some breathing room,

Take into account driving times. I was on a guided tour and we spent very little time on the major motorways. That may have been because our guides chose scenic routes or it may have simply been the only way to get to our destinations. What impressed me was how slow the driving was. Much of the time, we were on narrow 2-lane roads with curves and/or hills. And more than once, we were held back by a very slow-moving vehicle ahead of us.

I won't try to discourage you from one night stays, as that is what we did for 15 days in May 2015. We made a clockwise loop around the Republic and NI and saw a lot. It was a great trip. You do have too much packed in some of the days with driving and sightseeing. A real problem is on day 2 where you have Newgrange, Tara which are north of Dublin and Glendalough which is south of Dublin. This is not doable. Day 4 looks too packed as well.

Plan your route with Google Maps and add 25% more drive time. For most of our destinations that was very accurate.

Another really good planning tool is the Heritage Ireland website which lists many major tourist sights and gives detailed info on hours, costs, and average length of visit. Use in conjunction with the driving times to see how far you can go and how much you can see. You will find you have to prioritize and edit the wish list. PM me if you would like. Good luck. You will love Ireland.
