Well, I'm pleased to say that everything went really well both outbound and returning to Liverpool (using the Liverpool to Granada Ryanair flight). I was quite impressed with the airport...
I used Long Stay car park 1, which was no more than a five minute walk to departures. Check-in opened early and went smoothly (apart from the numerous people who ignored their booking info and tried to get away with more than 15kgs luggage,

so started moving all their belongings around as they didnt want to pay the surcharge, but didn't mind holding the rest of us up!!)
Although the queue to go through security was long, it was organised and moved very quickly.
The facilities/shops were good on both sides of security but I wasn't overly impressed with the choice of food after security - although I maybe didn't look around enough as I was really hungry!
On my return it couldn't have been more efficient. We were moved very quickly through border control and my suitcase was the second one off, so I was in my car within 20 minutes of landing and that included getting a drink at the shop.
Pity the airport isn't a little nearer, East Midlands will always be my first choice as its only 30 minutes away, but I would definitely recommend Liverpool.
