Andrews is not stopping there. Her lawyer, Marshall Grossman, told "Good Morning America" that Andrews will focus on sweeping changes in the hotel industry to protect against potential stalkers nationwide, calling for at least "minimal protection" in order to help secure the safety and privacy of their guests, such as better employee training.

Always use the chain lock in addition to the deadbolt. Using both protects the occupant even from people who may have gained access to master keys.

If you're suspicious of someone knocking on your door, call the front desk to make sure of their identification.

Make sure the front desk does not announce your room number when you check in and be aware of who is in listening distance.

Switch Rooms, Carry Flashlights

If you think you may be a target for stalkers, some experts recommend switching rooms or hotels frequently and trying to not stay in rooms with connecting doors unless you know the other occupant.

If you're traveling abroad, try to pick a modern hotel and be aware of fire precautions. It's best to be above the ground to discourage break-ins, but not so high that fire truck ladders can't reach you in the event of a fire.

Always carry a flashlight.
