I haven't been home since October 2019 and it's not looking very likely this year either...
I'm pretty confident we'll have our Vaccine by the summer but I expect ROI to be much further behind. I don't expect to be able to travel without some form of self isolation on arrival.
If this is say, 48 or 72 hours with a negative test then this is a possibility. My folks house in Dublin is largely empty these days so I could get my sister to stock it up with food etc. Do our quarantine and then head off west to where they live these days.
But if there's a longer quarantine still in place then there isn't much point really. Then of course, we'd need to get somewhere to stay because I doubt we'd be able to stay with them.
