Maybe I am making a mountain out of a molehill here, but IMO this is unacceptable at any hotel. The fact this has been posted here, and the hotels that therefore brings to mind, is appalling.
1. If the hotel is allowing girls to enter and have free reign of the rooms, what else are they doing against company policy?
2. If they are that lackadaisical about letting these girls in, what impression does it give off of their wider security?
3. Regardless of the country and how ‘locally acceptable’ that act is, why doesn’t the hotel’s head office better manage its’ estate and maintain absolute consistency across its’ security and guest safety agenda?
Fair enough if the OP doesn’t want to name the hotel, but I’d personally be interested to know so I can unequivocally avoid that brand and company going forward.
