Still not quite sure how you go about getting a connection to their network.
page seems to just be about eircoms wireless broadband access for 66euro a month + VAT but that then includes hotspot access too.
But I did find some stuff on the eircom.ie site about just access to the hotspots, not linkable though. They say that if you have broadband with eircom then you can subscribe to get access to any of their hotspots for 10euro + VAT a month, or for 25euro + VAT if your not an eircom customer.
It took some searching of their site, but I have finally found the pricing for the non subsctiption access which they claim "is available from reception and comes in the form of a scratchcard":
30 minutes €3.
1 hour. €5.
24 hours. €15.
7 days a week. €30.
Now does anyone know where the "reception" might be in the airport that you can pickup these
