It must go by area. HB & adrianb know cobraboy's area so their advice would stand. It wouldn't be the advice I'd give for some of the more tourist oriented areas, knowing what we know about some of the security companies.........

In the area where I live in PP (well heeled Dominicans) those who have security guards have them as employees of the family & loyalty is engendered through family connection, good salary & knowing the employees for many years. In tourist areas many security companies rotate staff so the loyalty bit can be missing. But cobraboy has the advantage of a Dominican fiancee whose family may well know some guard companies personally &
that makes all the difference.
