This year will be the first in a long time to have almost all the Irish goers in it, a fair chunk of let down UK people and the regular international peeps. There's going to be loads who had their tickets posted but didn't get them spending ages pleading to get replacements. For everyone else they've to find their actual ticket in a filing system that will be later described as "inadequate".
It will almost certainly be a shit show for the ages. I hope to be wrong but if I get through it in under 3 hours I'll be surprised. Plan accordingly.
ps this is all Wednesday morning talk. It'll be a comparative breeze if you are doing other days/times probably.
