The poor reputation of Ryanair is due to their cattle management, sorry, paying customer management.
Forget about them if you have kids : you'll be the last one on the plane, you will not find a seat close to yours for your 3 year old boy and you'll have to carry a lot of stoff by yourself. And if you have forgotten to check in online, you;ll have to fork out 60 euro for the pleasure to do that at the gate.
