As I said, we are getting the passports to "cover our rears"!!! Should we have to leave the cruise due to illness, etc. and fly back to the U.S., you CAN NOT re-enter without a passport...according to everything I've read. Hopefully it will be an expense that we really didn't need to incur but at our age, I'd rather be prepared!
Wrong.
So you would be stranded in a foreign country unable ever to return to the US???? Of course you will be able to get back to the US. It won't be easy though and the last thing you need is another hassle when you are stuck in a foreign country with medical issues or something else serious.
