In the last three years, I don't think I've ever waitied more than 15 mins at the carousel for the luggage. To be honest, apart from the long walk from the A side to the baggage hall (usually the far side of it, oddly enough), disembarking is usually pretty painless at Dublin.
While the arrivals are mostly easy, my blood pressure always rises a little having to fight my way through 100-odd RYR passengers fighting to get to the top of their boarding queue. IMO, there is simply not enough space to comfortably handle the number of passengers coming and going through the same space in the A-side extension. More passport desks would be nice too.
