Professional thieves tend to hang around hotels and resorts, especially the lobbies, looking for tourists and travelers who are easy pickings. Here are some travel tips that may help you feel safer and secure in your hotel room when you are traveling, or are on vacation.
If you can, try and book a room that is on the second, third, fourth, or fifth floors, as ground floor hotel rooms are more susceptible to break ins. Always keep in mind that hotel rooms above the fifth floor may not be accessible by many fire engine ladders if a fire breaks out in your hotel.
Make sure the door to your hotel room locks properly, and that all windows or sliding doors open and also lock securely. It's probably not a good idea to hang a "please clean the room" sign on the door knob when you go out, as it signals to a would be thief that there is probably nobody in the room.
It is advisable to not give out your room number to anyone that you do not know and trust.
There is a small, motion-sensitive, battery-operated, burglar alarm that can be hung on the inside door door knob, or there is a wedge-shaped alarm that you can wedge under the door that accomplishes the same thing. If someone tries to open your hotel room door, an alarm will sound.
Two less sophisticated methods you could use are to move a chair in front of the hotel door, or to wedge a standard rubber door stopper under the door. Both of these methods are also effective.
