What a fucking question...
OP, the first page on gov.ie about travelling outside of Ireland says:
Our general advice is: do not travel overseas for non-essential purposes.
How could you possibly think travelling to your second home right now is a responsible or appropriate thing to do? The kids haven't got an unexpected break from school. They're supposed to be home-schooling right now. This isn't the time to sneak in a holiday while you think you can.
Only last week RTE were reporting Ireland had the highest rate of new Covid infections in the world. The 14 day incidence rate shows that, on average, 1 in every 75 people were diagnosed with Covid-19 in the last 2 weeks. In some parts of the country it's as high as 1 in 39.
Because of these sort of numbers, we're on 5km restrictions, no seeing other households, most shops, schools, gyms etc. are shut. So many working from home. So many unable to work. All in an effort to get back to where we were as recently as the end of November.
And you think now is the time to get on a plane and go to your second home in Spain for a break? Have some cop on.
