Buy a leather case for your passport. Looks good and keeps it damage-proof.
Memorise your passport number, issue and expiration date so that you don’t have to keep pulling it out each time you need to fill a form.
How safe is a hotel “safe?” Nobody knows. We suggest you keep your passport pouch in a thin ‘money belt’ worn under your shirt or inside your trousers.
Pack an extra set of passport photos. Also scan and email yourself the passport’s information page. Keeps you consulate-ready if you lose your passport.
If you go to a bar, restaurant or café, be careful to keep your purse, whether or not it has your passport in it, hooked over your knee.
