Some Holiday Inn hotels adopt a ANPR system.
Failure to be a guest at the hotel or book your EV in at the reception desk ( take a photo ) while charging, can result in a penalty arriving at your address.
Some will allow a small drop off time, but after this you will get nicked !.
Ask me how I know.
About two years ago, I dropped off two family members at Manchester airport. They where using one of the hotels before taking an early morning flight, the following morning.
A week latter I returned to the same space to pick them up on there return.
I picked them up on the same hotel car park.
There was a small delay of about 10 minute reaching the car, because there was a delay with their baggage.
About two weeks after, I received a penalty/ fine through the door from the private company that was employed by the hotel, to enforce the car park enforcement.
The fine was for £100 - but if I was a good boy and paid up in less than two weeks, they would kindly reduce the fine to the bargain price of £60 !.
The fine included timed images of my car arriving and leaving the car park.
A bit annoying when only about 30% of the car park was being used at the time.
They also included a zoomed in photo of a small sign, that had been screwed to the wall, next to the reception area door.
It did explain the T&C’s of the car park.
Unless you was carrying a set of binoculars in your car, you where never going to see it though !.
Polar rapids tend to be located in Holliday Inn car parks.
The last time I used one of these units, there was a tablet on the reception desk of the hotel.
You just need to key in your registration when prompted and make sure it is 100% correct.
It will give you a brief green tick

on the screen, take a photo !.
An expensive lesson learnt, if you get it wrong.
I have been driving for over 45 years and never received any type of penalties, until this one arrived !.
I was absolutely gutted ?!.
