My Advice - Travel with Valid Passport
If you read all the rules and regulations, you may find that for your particular travel plans, you can "get away" without a passport. For example, a closed-loop cruise does not require a passport for sea transportation. However, should you find yourself needing to return home by air, you could now be faced with a problem since air travel has a different set of rules.
Also note that passports must be valid for 6 Months after the end of your trip (in most cases).
