Dublin is looking strong as the location for this event based on convenience and cost; as a direct entry point to Ireland it is serviced by the main Budget airlines and easily accessed from most European cities.
From the US I fully understand the flights can be expensive, especially as this will be in the Summer season. Aer Lingus can have great offers for early Summer flights and they generally go on sale just after Christmas. I am attaching current link for cheap flights (to be taken before end of April) and will refresh this link once the Summer sale starts.
http://www.aerlingus.com/travelinformation/weboffersfromireland/irelandtotheusa/There are low cost accommodation options for Dublin, budget hotels, room sharing or city apartments will keep the costs down. I will source the best of these options and provide approx. rate for 2/3 night stays. Dragonfly is correct, if you know what's involved in attending it will make the decision making easier. Having said that the greater our numbers the better deals to be made with hotels etc., so even if you are only 'considering' attending please do let me know and I will look to secure the best possible rates.
I think I might be the only LBS living in Ireland, at least the only one connected to the Site. I am more than happy to open my home to anyone trying to make the weekend. I already have two LBS planning to stay with me but if this might be an option for anyone else, just PM me and we can talk.
I would like to see as many people as possible travel, so if there are any other suggestions on how to keep cost down please do post here.
