MANBLK - before you attend or sign anything you also need to read the following (see post #7):

Ryanair are very short of people at the moment (and will behave relatively reasonably towards prospective employees - at least until they sign up). You will be bonded for 5 years (and that will be interpreted to have the consequences that
they decide). You will be on a deal which was rejected by around 90% of existing Ryanair pilots. This deal, as per the
Flight ad offers you a "stable 5 on 4 off" roster. Ask them at the open day for a list of the exceptions and possible changes to the "stability" and "4 off" part of the deal. Ask them if it is true that there are pilots who have signed on but not been paid for periods of 6-10 months (and ask will it be possible to get it in writing that it will not happen to you).
The salary quoted is "grossed up". You might care to ask them how the salary figures are calculated, since nobody other than them seems to understand it (but do understand being paid less than they were told). Before you leave where you are, you need to gross up your current salary up for comparision.
Finally, it would be really interesting if somebody like you did ask them these questions and reported back here what answers they are giving.
