Nothing wrong with Ryanair if you read the rules and apply a bit of common.
Bag Drop, check-in online and print your boarding card on a standard A4 page (not double sided and don't be a cheapskate and print 2 per page). Bag drop opens 2 hours before and shuts at -40 so just make sure you turn up between them times as no rewards for turning up first or last. You CANNOT pool your bags so don't argue with them if you buy BAG1 for 2 passengers and turn up with 17.0 and 11.0. If you have a non-EU passport then you need to go to the Visa Check desk and get that stamped as you will turned away at the gate if you don't.

Hand Luggage, if it fits in the crate it fits and if it doesn't you get charged £40. Don't bother buying a "soft shell" bag that is exactly the dimensions and cram it to the brim as it obviously expands beyond the dimensions. All shop purchases, mini pouch bags and laptops must fit inside one bag.

Boarding, they call the flight -40, priorities queue down first and then everyone else behind. Loading front and rear steps so see where the "priority sheep" go first and you go the opposite side. Staff are only rude if you are arrogant to them so just help them out and they'll get you there on time. Gate closes -20 and you will be offloaded with no offload calls so don't wait until the queue dies down as you'll be booking another flight.

On Board, you pay for the flight and so you get the flight. It goes on time and it goes quick. If you want pre-boarding drinks etc.. then fork out the £100s for a full-service flight. Buy a meal deal at the airport before as drinks and food are expensive on board. Put some films on your iPhone and just chill out and relax. Ryanair I found are fierce with agents so expect all your bags on time as the agents will get hammered for any lateness.
