I married into a large Irish family and goodbyes take bloody forever as everyone has to have a ten-minute conversation with everybody else on their way out the door. Irish ghosting goodbye my eye.
The Irish goodbye exists because the alternative is a long ass poetic farewell. So, if you want to avoid it, you give a couple people key goodbyes and check out.
...or just a sneaky nod to someone who understands what you mean. They're left to tell people that you went home, if anyone asks. Just don't do that when your round is next.
