Stories such as this really put me off visiting hotels. In a perfect world I would just walk to a discreet in call venue and have total privacy.
It sounds as if the Hotel in question suffers from people parking illegally in the hotel, probably not to catch punters out but it's all a moot point when they've got CCTV and they've clocked your time of arrival/departure. Obviously pay the fine ASAP no point this dragging on, what you tell the misses will be up to you, but I expect some tall tales or on the knees grovelling may help. Thanks for the heads up, in future maybe taking a 5 minute walk from the local NCP would be good advice for punters who visit Hotels
