If you are coming in from Dublin Airport there are a few options on getting to the Hilton hotel, Charlemont for Sql Saturday Dublin 2014
There is a taxi rank to your right as you exit the terminal at Dublin Airport. It's well managed by Dublin Airport staff and any queues move pretty quickly. A taxi to Charlemont Place will cost you around €30. the Hotel can help you book a taxi back.
If you are travelling around Dublin and want to book a taxi there is an excellent App for mobile phones to book and track taxis. You wont need this at the Airport as they have a 24 hour taxi rank.
By Aircoach and Luas
There is a dedicated coach between the airport and city centre that is very comfortable and has WIFI. It also runs 24 hours and has GPS tracking on its web site to see where the coaches are!
From the city centre there is a very good light rail system and the Hotel is only two stops south of the city centre (Stephens Green)
take the Aircoach Leopardstown service to Kildare Street and then walk around the corner to the LUAS stop at St. Stephen's Green (just at the top of Grafton Street). It's about 5 mins walk. From there you can take the LUAS two stops to Charlemont which is right by your hotel.
The Aircoach as far as Kildare Street costs €8 single per adult and €14 return. The LUAS costs €1.50 each way.
Just walk outside the airport and you'll see blue signs for the Aircoach to Leopardstown.
Ok you cant actually cycle from the Airport to the Hotel, but if you are sight seeing there is an excellent bike rental system in Dublin where you can rent bikes and drop them off at set points.
The site below shows you where the pickup points are. There is one bike station right outside the hotel.
