You will be able to find a number of ATM's that let you withdraw cash from your foreign account but it is always better to keep some cash with you in case the ATM cannot help, or you lose your card. Any documentation that you are carrying around, it is recommended that you have more than one copy of it. It is advisable that you keep both copies in different pieces of luggage, therefore, if you lose one luggage you will still have the backup documents and copy in the other.
