Getting to Dublin
Aer Lingus fly direct to Dublin Airport from many European and US cities. There are also several other airlines who provide either direct flights or indirect flights via London. These may be cheaper, but will likely be longer due to the connection in London.
If you're flying from Europe, Ryanair provide low cost flights from many locations direct to Dublin Airport. Beware that Ryanair often fly from smaller airports which are often more difficult to get to.
Getting from the Airport
Aircoach provides a frequent service connecting Dublin Airport to the most popular Dublin hotels and also to UCD. Prices are approximately €10 one way and €15 return. The service runs 24 hours, although buses are less frequent during the night. Attendees staying at the recommended hotels or coming straight to UCD should take route 700 towards Leopardstown.
Public transport in Dublin typically runs from 7AM until 11.30PM, and is available in the form of bus, rail and tram. All three accept the leap card, which is cheaper and more convenient than cash. Typical cash fares are approximately €2.50 per journey, with exact change required on buses.
The Talbot Hotel provides a complimentary shuttle bus service which is available for transporting people between the hotel and UCD. This must be reserved in advance.
