As everyone else I wanted to fly to Dublin on friday, too. While packing the day before I noticed I could not find my identity card. To make it short: I was at the airport with a copy and several other papers that (more or less) state my identity, but no luck. There is no way to travel without a valid identity card to Dublin.
So I'll take another plane 5 days later, on wednesday. There is a small chance (maybe 5%) I might be able to come on monday already. Let's see... :)
All in all I'm missing almost all of the highlights, just look into the conference program.
Lesson learned: Start packing 1-2 weeks before. sooooo stupid :(
