Hi Josey,
It's so exciting you're planning on visiting us. :) What type of
travel documents you need totally depends on how and who you are travelling with. Are you coming over by ferry or plane?
If you get in touch with the
ferry or airline company you've booked with, they will gladly tell you if your UK license is a valid travel document for Ireland.
What do you have planned for your trip so far? We'd love love to hear more about your itinerary. :)
Warm regards,
Melin
