We were meant to use the train to Cologne airport, which would have cost us 6 Euro per person for the hour-long trip (!), however due to electrical storms, all trains were suspended that day, something I have never experienced before so my father drove us to the airport instead.
Ryanair make you check in online and print out your boarding pass, which we did. Apparently they charge heaps (I believe 70 Euro each) for boarding passes that need to be printed at the airport so we made sure not to forget our print-outs. At check-in, we were told that the flight was extremely full and I only counted one spare seat on the plane when I did a walk through the cabin. That seat turned out to be in our row so we had three seats to ourselves.
We later found out that one of the reason why the flight was so full was that a flight to Palma de Mallorca had been cancelled. Ryanair being a low-cost carrier rebooked everyone to the Barcelona flight, with an ETA of 11.20pm: the group we talked to told us that Ryanair then booked them on a flight to Palma leaving at 6.00am the next morning, with no accommodation offered. True LCC spirit.

Thinking about this again, maybe this was a case for compensation under EU regulations but I doubt that Ryanair would have been forthcoming in sharing this idea.
Another consequence of the full flight was that we were basically ordered to check in our carry on, however we refused to do this as we didn’t want to see our laptops in the hold. The check-in lady was quite grumpy when we told her but she accepted it, and it later turned out that there was plenty of space in the overhead lockers.
Priority boarding can be added to bookings on Ryanair for 3 or 4 Euro (I’m not sure exactly but it is not much) and the people who did had their boarding passes scanned earlier than other passengers, only to be standing inside the “finger” and waiting there. Yes, they boarded the flight slightly earlier and I guess they had more time and space to store their hand luggage, however this seemed like a waste of money to me.
The flight itself was uneventful. The pilot was very chatty with constant updates and apologies about the delay, whereas the flight attendants were busily spruiking their wares, which also included scratch cards. Interestingly, not a single word of German was spoken and all announcements were in English and Spanish only.
Some photos of the flight below. A short summary: if everything goes well and one knows and obeys the rules, I think Ryanair is a suitable carrier for short, intra-Europe flights, particularly if main airports are used, as in our case.
