A quick search to Google of any hotel will give you a list of reviews, and it just takes one bad review to ruin the reputation of the establishment. It actually seems unfair seeing how challenging the hospitality and hotel industry can be. As hotels deal with a revolving door having guests from all over the world.
There is literally no telling as to what kind of pests they might be unwittingly harbouring on their luggage, or clothes. Once the pests check-in, they will make themselves at home in your hotel and also introduce themselves to every and any guest they encounter. Post which, it’s only a matter of time. Before guests are blasting all over the internet about your hotel.
