I guess my situation is rather different:
I was on the Greek Cruise Ship that hit volcanic rock, killed 2 passengers, and sank in the middle of the Aegean Sea. (
http://www.cbsnews.com/stories/2007/04/06/world/main2655363.shtml?source=RSSattr=HOME_2655363) We were on board and lost everything. All our luggage, our passports, digital cameras, clothes, medication, purses, money, you name it and it was gone.
We had no time to grab anything. In addition, we were on the 2nd floor (bottom floor) of the ship and we were afraid that the water tight doors were going to close.
From this traumatic experience I've learned a couple of invaluable things:
1. ALWAYS make copies of your passport when you're traveling overseas. Leave one copy at home with friends/family, bring one copy with you and keep it on you at all times, and send a copy to your destination.
2. While you might not always have the option (like us) to grab things before you go, bring extra medication.
3. Always pack 2 days clothes and necessities in your carry-on (obviously I didn't learn this one from the ship).
4. Always bring 2 credit cards and more than you anticipate bringing.
I hope these people can get home soon. It truly is miserable to be stranded somewhere.
