GB leaves the EU

When will your trip be? It will take time for the UK to actually leave.

Cutting ties with the EU will be a two year process.

Book your tickets, you'll be fine. It will be interesting to see what develops between the Ireland and Northern Ireland border but that will take time.

IMHO the vote is stunning. Fear mongering won.

You will be fine. As already mentioned, it will take at least two years before anything happens anyway.

Enjoy your visit to our beautiful Island, and also to stunning Ireland!

Not sure its completely about fear mongering-more about being run by officials you have a say in electing. I can think of 4 good reasons to leave and none of the four are about immigration.

Just to mention as well, The only passport border between the countries you have mentioned is between Ireland and NI/Scotland, as the last two are in the UK and Ireland is its own country.

Again, just to put your mind at ease, your travel plans will not be affected.

If you need any help, let me know and I'll help as much as I can. :)

The sky would fall only if you didn't vote to remain. The fearmongering lost this time.

It will take several years to get this all sorted out. Unless NI, and Scotland vote out of the U.K. in the next week or two, you won't have to worry about borders within the UK.

Society has been in the U.K. for 3000 years. They'll be there next year and the year after too.
The confusion is just temporary, and it'll take quite sometime for Great Britain to actually terminate their membership in the EU.
Just go and enjoy your trip.

Thank you for all of your replies! We figured it would take a little while for all of this to work itself out. We will be traveling late July into August 2017. We will be ending the trip in Belfast for a three day family reunion of sorts and are beside ourselves with excitement. The plan is to fly into Shannon and spend some time touring the Southwest and South, eventually making our way to Dublin. I've allotted about a week and a half for this. We thought we'd then go to Donegal, then over to Londonderry. We hope to drive the Coastal Causeway, possibly take a ferry over to Scotland and back before ending with the 3 day Clan gathering in Belfast and flying home from there. As you can see, we are in the beginning stages of planning. Our travel agent would like us to have a game plan by September so I have been trying to form some type of list of must dos. We may have to bump Scotland from our list and go there next time, but I would love any advice you all could give. I have wanted to visit Ireland my entire life and I'm having a very hard time narrowing things down.

Thank you so much!

Northern Ireland is part of the UK (Giant's Causeway included) so I'm not sure why you'd consider dropping Scotland.

I would check whether there are currently substantial drop-off charges if you rent a car in Ireland and return it in the UK (Northern Ireland or Scotland), if that's your plan. There are generally big charges between EU countries on the continent. If they do institute checkpoints for border crossing, it would probably be nothing more than a formality.

Thanks for the tip on the rental car, Chani!! Giant's Causeway is most definitely on my list. We've considered not going to Scotland because of time. If I could dedicate 2-3 days in Scotland what would everyone recommend we do?

"The only passport border between the countries you have mentioned is between Ireland and NI/Scotland"

This is incorrect. Currently the Republic of Ireland and Northern Ireland are both members of the EU, and there are no passport controls going from one to the other. This past April I took a bus from Dublin to Belfast, and the only way that you knew that you were entering a new country was (probably) a "Welcome to Northern Ireland" sign which I did not see. I was like driving from Washington State to Oregon. Of course this all changes in two or so years when the UK's divorce from the EU becomes final.

Will it? No one knows.
