Went last year and found it far better than the Irish Times Higher Options one. Its a great spot for the CAO kids to chat to reps from the different colleges/universities and confirm to themselves if they need to avail of the 'change your mind time'.
The kids met/chatted to people who were working for a few years in the fields that they were considering and they found this worth the visit.
For anyone considering Cadetships there were stands for Air Corps/Army etc.
