Hi Judith,
That's a great question you are asking there. When will you be making your way to Dublin?
Transport for Ireland is advising travellers to
allow extra time for their journey, so that's something to keep in mind. Since you're planning to travel by taxi, it might be a good idea to contact your taxi company and ask them for guidance. Your hotel might be able to advise you on the best way to get to them as well.
If the protests are ongoing when you're making your way to the station for your trip to Westport, you'd want to make sure you have plenty of time to get there. Is your hotel close to Heuston Station?
I hope this helps and that you'll have a wonderful trip.
