It's lovely to hear that you will be over for a visit towards the end of the year and taking in some of the wonderful sights the north of the island has to offer with your group!
We have a wonderful approved accommodation
search page which you may find handy for finding some of your accommodation needs as you travel. Enter a location and accommodation type from the drop-down menu for information on what is available in the area. It would definitely be a good idea to stay overnight either in Derry~Londonderry
during this time as the roads are mainly rural and distances are not an indication of the time it would take to drive from Dublin around and back again especially as there is so much to see on the route and the days are getting towards their shortest.
From Galway, it will be possible to visit the Cliffs of Moher by public transport, Bus Éireann
has a 350 service that runs from the city towards Ennis stopping at the cliffs. There is a wonderful journey planner from Transport for Ireland
that will be useful to work out your transport needs to make some of the other locations. Killarney
is another popular place to visit, the national park is a great spot and Muckross is another place that would be lovely to stay and explore all the local area.
I hope this gives you lots of inspiration, and hopefully, your fellow members and some industry partners will be able to add to this list with a few ideas!
