Knowing how easily things disappear - for whatever reason- I colour copy our travelling documents, my International Driving Permit, all or any travellers cheques we may be taking and all my credit cards, licenses, etc. As for the IDP it's now become necessary as some insurance companies are refusing coverage/accident repayment..telling their policy holders they were in breach of contract because even though they could use their drivers license in the country they were visiting - they did NOT have a valid drivers license for that country. An IDP IS a valid license for most countries. Needless to say...keeep it seperate from your drivers license so if one is stolen/lost you still have the other.
