Prebooked the mid term car park. when I got there, there was no space. The stewards were getting people to park in lanes, which could have resulted in cars getting damaged. I was moved to the short term car park. The short term car park is atrocious - it is the worst car park I've seen. There is no proper surface, there are few proper markings, most of the lanes are blocked at the ends so you have to reverse all the way back if there is no space - it is just chaos. The mid term car park seems just as bad. Leaving your car at Luton airport is not a pleasant or stress-free experience.
