Stena Line goes from two places in Dublin. Dún Laoghaire, which is a port on south of the city is about 14 miles or 23 kilometres from Dublin Airport. There is also Dublin Port in the city, which is about 8 miles or 13 kilometres from Dublin Airport.
About 6 miles.
About 8 miles or 12 kilometres.
About 160 miles. Some or all of that would be by ferry or air.
It is about 147 miles or 225 kilometres.
About 160 miles or 250 kilometres.
There is no actual place called the Dublin Exhibition Centre. There are a number of places in Dublin that have exhibitions, most notably the RDS (Royal Dublin Society). Dublin Airport is about 6 miles from the city centre. The RDS is about 2 miles from the city centre, on the opposite side than Dublin Airport. Most of the other places where they have exhibitions are close to the city too. So wherever the place you are referring to is, it is not far from Dublin Airport, within about 12 miles.
Blarney is in Cork, so to drive there from Dublin airport would take at least 3 hours on the motorway and could be more in heavy traffic.
From Roscommon town to Dublin Airport is about 100 miles or 162 kilometres. Depending on where specifically in the county of Roscommon you are going to, the distance would differ, but not by a large amount.
Dublin would be better. Shannon is just a town near Shannon Airport. Dublin is a city with many attractions, so there is far more to see and do.
It is 433km or 4 hours and 13 minutes. Hope that helps!
At an absolute minimum, you might do it for €20. There are better options, as Dublin Airport is well served by buses which will bring you past Temple Bar for a far cheaper price. They might not bring you to exactly where you are going in Temple Bar, leaving you with a bit of a walk and you might have luggage, but it is a better option.
It's 50 Mins on Lingus to Heathrow, around 65-70 mins to London City using Air France
