Unfortunately it's the handling charges that make Dublin International so expensive. When we used to be based there, we didn't have any handling charges (and parking was an annual arrangement).
That just left landing fees (well movement charge) which could be as little as €0.50c! depending on the time of the date, and day of the week.
More normal would have been about €9 for a take off and landings, so not expensive. Unfortunately the handling agents know how to charge
On the other hand, as you say, Vanessa is lovely in every sense
