Hi and happy new year,
My wife and I flew Ryanair for the first time last year from Edinburgh, no problems at all about the same service provided as Jet 2 and Thomas Cook (flight only) but slightly better than Easy jet.
Flying Ryanair again this year in June again from Edinburgh, whatever you do its all ways going to be a case of ya pays ya money and takes ya chance. I would suggest that you pre-book your seats this saves the worry of being separated on the aircraft.
We have done independent for a number of years (apart from a couple of specialist holidays) and have never been disappointed, we all ways treat it as an adventure with no great expectations therefore no great disappointments.
One is for sure and that is Arillas never disappoints.
You can take endless tips from numerous people but until you take the plunge you will never find out.
Whatever you choose we hope you enjoy your experience and your holiday
