Separate documents and backup payment methods, use official transportation channels whenever possible, and keep accommodation contact information in a readily available format.
Prepare a small recovery plan
Think ahead about what to do if you lose your card, contact your hotel, or seek medical attention before you need to. Ask your accommodation for the latest local information.
Stay alert, don't be anxious
Crowded traffic, nightlife, and unfamiliar payment requests are worth watching. Calm and daily caution is more useful than fear.
