Health insurance
If your health insurance doesn't cover you, you should consider purchasing a short-term health and emergency assistance policy designed for travelers.
Hotels
Upon entering your room, you must do a thorough security check. For safety, the door should have a peephole, as well as a safety chain or latch that operates from the inside. Make sure to use the locks. Don't open your hotel room door without verifying who is outside. Always carry your hotel address with you.
