Hotel room safes offer no protection
There are heaps of videos on YouTube showing just how easy it is to open a locked safe used in most hotels. At best they are designed to keep honest people out.
The purpose of this email is just to warn you that one of the worst places in the world for theft out of locked hotel safes is Bali.
Please think twice before leaving your cash, jewelry, credit cards or passport in a safe unless it is a quality 5 star establishment. Even then, they may have a safety deposit box system and that would provide better security for you.
