In particular, it would be convenient for me to land in Dublin EIDW,

plane on the apron : 46€!)

Anyone here could share his/her first hand experience ?

You seem to be correct:

For truly first hand information, why not just call them and ask?

Don't forget that Dublin is the home base of Ryanair, so they may be
actively discouraging private pilots to bother them.

Even though it is a professional pilot's forum,
they have been remarkably polite and helpful the
few times I've posted there.

The majority of the users seem to be UK-based and
well informed about anything aviation-related.
