The U.S. State Dept. urges all Americans to exercise caution, maintain heightened security awareness and be vigilant to any unusual activity. It is worth the nominal investment. Review all documents in advance for important guidelines and travel tips. Check either the cruise line or tour company web sites for information. Prior to leaving home, call the airline for flight departure confirmation.
Security screenings take additional time.
Make sure all luggage is clearly tagged. Make sure all necessary medical items, your passport and other travel identification are with you.
