I would like to get to county ennis but it is a long way from the airport.
Ennis isn’t a county.
If you mean the town of Ennis I think you will find it’s only half an hour from Shannon airport but if you’re flying into Dublin it’s still only about a hundred and fifty miles away and accessible by train or road.
Nowhere in Ireland is “a long way from” anywhere, the entire country could easily fit inside many US states.
Ennis is a town in Co. Clare, not far at all from Shannon airport.
