We parked at Reus for 3 weeks over Christmas and the car was exactly as we left it.  We've also done a collection and drop off this month without any hitches so I think you just have to be careful choosing where to park.

We travel to Luton with Ryanair, as have family and friends that have visited and we haven't had any problems with them at all.  We've just booked 2 return tickets for son & girlfriend for the end of April and the total cost of the tickets including airport check-in and baggage was £83.40.  If we had booked same dates, similar times Easyjet Gatwick to Barcelona it would have cost £213.94 and we would have the added time and expense of driving twice the distance and parking at Barcelona. So I certainly don't have any complaints re costs.  I guess it's horses for courses?

We have also booked ourselves a couple of return tickets to Sevilla (new route) in October and they cost just under €60, which I'd say is a bargain.
