answer:Carry your passport with you unless you have a secure place to leave it; it’s valuable. (You won’t be leaving it in a hotel room will you?) You can purchase a passport-size leather or vinyl case that hangs on a cord around your neck, beneath your shirt. But do make several photocopies of it, one to leave at home with your parents and a couple to leave in your suitcase, just in case something does happen to your passport. Yes, change your currency at a bank. You’ll pay a much higher rate for the service at the airport. If you need a little cash in hand for use on arrival, you can request it from your own bank here at home before you go; it’ll probably take a few days.
