In order to stay safe in hotels and the hotel property, it is important that you follow all hotel rules and regulations. But as well as these, below are some do's and don'ts that will help you stay safe when staying in a hotel abroad.
Always shut and lock your door when you are inside. Use the chain also. It doesn't matter whether you are only inside for five minutes.
If your hotel key card came in a little cardboard folder then you should get rid of this and definitely not carry it around with you. This will avoid strangers being able to know where to find you.
Have fun whilst you are away, but in moderation. Don't get completely wasted and then stumble through the streets trying to find your hotel. Drunk tourists are easy targets for muggings.
Contact the hotel's reception desk if you think there is anything wrong or odd about your room. If you see anyone hanging around that looks suspicious, then report it to the desk and insist (if you must) then someone investigates that person.
Try to avoid taking expensive pieces of jewelery with you on holiday. If you have to, then keep them locked in the hotel safe, usually found in the wardrobe, when you are not wearing them.
Don't leave any valuable items on show in your room. You may not want to take your laptop with you everywhere but sometimes it is necessary. Try locking it in your hotel safe if you really don't want to take it with you.
Don't let strangers into your hotel room. This includes the hotel staff if they come knocking on your door. Use the little peep hole in the door to see who is there. Don't order room service, but if you don't want to go to a restaurant then pick up some food outside the hotel and take it to your room.
