Well i'm back to give you my experience and I have to say they were fine, I have to say I was v pleasantly surprised.
We weighed and weighed again our suitcases and carry on luggage at home beforehand so made sure we were ok with our weight restrictions. There was no messing if you were over though I think my Mum was something like .5 over and had to take it out and put it in her handluggage but they were fine with her and it was her own fault anyway (well she claims it was a ruse by Ryanair to try and charge her more
)
The queue to check in our luggage at Liverpool was pretty long but moved quickly enough. The girl at the desk looked like she'd have rather been anywhere but where she was but got us through quickly which is all I wanted really. Very glad we paid for priority boarding as we walked straight into the priority boarding queue at the gate where we waited for a few moments (not many of us) and then we walked straight onto the plane.
The flight attendants themselves on board were nice enough, the plane was erm well basic, the emergancy landing info on the back of the seat had my Husband (who hates flying anyway) desperatley trying to avoid looking at it all flight! but the seats were clean , it was an early flight though who knows what they'd have looked like by 11pm.
Food and drink on board was expensive. I think I paid £2 for a Water and £3.50 for a coffee and my daughters snack box was £5 but I was warned.
The flight left on time and got us there early, someone mentioned earlier then landings were bumpier though and they definitly were. V bumpy landing home in Liverpool and it felt like the pilot had literally thrown the plane down onto the tarmac at Alicante.
All in all it got us there cheaply, and safely and a fab holiday was had by all which was pretty much all I wanted. Thanks to everyones experiences though it meant we were prepared!
