In light of the recent sinking of the Costa Concordia my travel tip for Americans is to register for STEP -https://travelregistration.state.gov/ibrs/ui/ Smart Traveler Enrollment Program
STEP is a US State Department program where you can register your trip information in case of an emergency. While we all assume nothing will happen while we are away, the reality is that things do happen (London tube bombings, Madrid train bombings) and when we're overseas it's much more complicated. You may need a new passport, clothing, basic necessities, money or transportation. The US Government, your hotel/travel company and your family will know you're overseas. The easier it is to get in touch with you the easier it is to take care of all of those issues.
