The bottom line is you should have been able to register your details at reception on an iPad like many many hotels and that would have been your permit and all would have been OK. Problem was due to Covid or whatever reception was not open and you could not. That really is all there is to it. All the BS that followed is just that BS. The signs are (deliberately?) misleading and the system is clearly flawed but that is the system, the chargers are supposed to be open to all Tesla owners.Hotel have now agreed to instruct their contracted firm 'Civil Enforcement Ltd' to cancel the fine. I still don't know for sure what the system is - one poster writes here that there is no permit, but both Civil Enforcement Ltd and hotel staff were adamant that only permit holders are permitted to use this charger. And yet another member of hotel staff was equally adamant that no permit existed.
I feel like some of this is maybe a legal mechanism. As now I am looking for these tiny signs, I have spotted that my local Shell station actually has a very similar one saying that the Shell station is private land and for permit holders only. But I haven't ever been fined while filling up a petrol car there. Maybe there is some legal reason that you can't just make parking 'forbidden' but you can say it's only for permit holders?
I wrote to the hotel manager with a picture of the red signs at the Northampton site which to me are much clearer that an action is required and what that action is, suggesting that they may consider having similar signs.
Will definitely not visit this particular supercharger again. And will try and stick to the motorway services superchargers or the Northampton one where I know the system. If the other non-motorway locations are as abstruse to use as this Kings Lynn one, I am not taking a chance again.
People have actually been fined at petrol stations while charging for being there too long. In some places they have APR cameras to stop people using the forecourt as a carpark with a max stay of 20-30 minutes. OK if getting Dino juice and or a snack. not so good if you are using a 50KW charger.
