Security guard in hotels must move around to patrol the various parts of a property. They check the doors and stairwells to make sure the locks are secure and no danger is lurking. Most hotel managers like to see the security guard in the lobby, especially when large groups arrive and during busy morning and afternoon times to provide guests with a sense of security. Guards must patrol outdoors as well as room hallways and activity areas, such as the pool and spa. Large properties may employ a number of guards to keep up patrols and maintain communication through radios.
