Maple Manor Parking @ Gatwick
Since Google gets stuck in an infinite loop asking me to log in to leave a review, I'll leave a few notes here instead.
I booked 7 days' parking and a hotel room before my early flight through Holiday Extras, and it all went reasonably well - pick up of the car was fine, and it was waiting for me on my return. It had a few extra miles on it (about 25, from memory) - not excessive as they do make it clear they park the cars off-site. However, the battery was flat as a pancake and I had to call out a tow truck to jump start me.
The car has a central locking fault which I have yet to get fixed, so it's quite possibly my own fault that it drained its battery inside of a week. I find it hard to believe that it went flat on the run back to the drop-off point, so the parking staff clearly gave it a jump. They could at least have taken 10 seconds to text me a warning so I knew to call out the tow truck when I landed, thus avoiding most of a 50 minute wait after midnight. Even better, a missed business opportunity - they could have offered to stay with my car with a battery booster on hand, e.g. for £20 (or even £40), and I would happily have taken them up on it. Four out of five there, chaps.
My radio and seat had been fiddled with, but this didn't bother me nearly as much as many other reviewers - and they had used a floor cover to avoid getting mud in the car.
