Vice President of the Irish Travel Agents Association, Clare Dunne, says their sector's had a very busy week as people prepare to travel:

We started to get calls almost straight away from people inquiring about could they travel in July, August this year; could they start making plans for later in the year, for next year. I think once they had it in their hands and they saw it, and they realised, yep this is actually happening, they then felt comfortable making plans."
