Flight
Dublin is the best airport to fly into. Aerlingus linked above have some good deals and some package options if you want to extend your stay. Book whatever flight/airline that works for you - I would suggest a flight leaving on Thursday 17th at the latest as that will get you in on Friday morning, giving you time to get over the jet-lag before the wedding on Saturday!
Hotel
This hotel would be great to stay during the wedding, Friday/Saturday/Sunday night. It's very close to the venue and we will have transportation picking up and dropping off guests the day of the wedding.
Hotel
This B&B is super close to the venue!
