Friendly reminder to check your passport expiration date before you leave. Your passport just needs to be valid for the duration of your stay (i.e. no need to worry about an extended passport validity requirement to enter Ireland from the U.S.).
We recommend flying into Shannon as it's closest to the venue - 30 minutes and you're there. Taxis and Ubers are readily available.
Dublin is approximately 2 hours from the venue. To get to Adare, you can either i) Rent a car to pick up at the airport, ii) Uber, taxi, or car hire direct from the airport, iii) Direct bus with Flight Link, or iv) Train from Dublin Heuston Station to Limerick City followed by a bus or taxi/Uber.
