Don't forget you can register your travel with the U.S. State Dept. which can "supposedly" help in desperate times like lost passport, cash stolen and you're destitute and of course help should a natural disaster occur.

From their FAQ Page - Consular officers at Embassies and Consulates can assist U.S. citizens who encounter serious legal, medical, or financial difficulties overseas. For example, if your passport is stolen while traveling, we can assist you with obtaining a replacement so you can continue your trip. We can also provide the names of English-speaking doctors or local attorneys, provide loans to destitute U.S. citizens, and provide information about dangerous conditions affecting your overseas travel or residence. We also perform non-emergency services, helping with routine passport applications, absentee voting, selective service registration, receiving federal benefits, and filing U.S. tax forms. Consular officers can notarize documents, issue passports, and register U.S. citizen children born abroad. Most embassies and consulates have web sites with more information about their citizen services.
In a crisis situation such as a natural disaster or severe political instability, the Department of State often takes an active role in providing information and assistance to U.S. citizens in the affected area. Visit travel.state.gov for more information.
*Please note that STEP enrollment is NOT considered proof of U.S. citizenship. If you apply for any services from the Embassy or Consulate while abroad, you will be asked by the consular staff to provide proof of U.S. citizenship. (If you are seeking assistance because your passport has been lost or stolen, we will work with you to obtain alternative proof of citizenship and identification.)
