Problem solved.
Aer Lingus to Amsterdam
Down to the basement to get a train to Rotterdam
Sleeper from Rotterdam, arrive at destination Saturday morning
Two extra days ski-ing, save a good few €x00, arrive early in the morning, depart Dublin airport at a non-loolaa time. Can't be beat.
Incidentally, I checked my receipt for last years trip for the same busy weekend last year. I booked Ryanair flights in October 2006 for the New Year weekend - cost €1,200ish. Cost now for the same dates (different times though) is €2,000ish. I know Ryanair are just performing revenue maximisation and that's one of their jobs, but they have just lost business this way.
