Crime aboard cruise ships has occasionally become headline news, thanks in large part to a few well-publicized cases. Most people never have any type of problem, but you should exercise the same precautions aboard ship that you would at home. Keep your valuables out of sight—on big ships virtually every cabin has a small safe in the cabin. Don't carry too much cash ashore, use your credit card whenever possible, and keep your money in a secure place, such as a front pocket that's harder to pick. Single women traveling with friends should stick together, especially when returning to their cabins late at night. When assaults occur, it often comes to light that alcohol, particularly overindulgence in alcohol, is a factor. Be careful about whom you befriend, as you would anywhere, whether it's a fellow passenger or a member of the crew. Don't be paranoid, but do be prudent.
Your cruise is a wonderful opportunity to leave everyday responsibilities behind, but don't neglect to pack your common sense. After a few drinks it might seem like a good idea to sit on a railing or lean over to get a better view of the ship's wake. Passengers have been known to fall. "Man overboard" is more likely to be the result of carelessness than criminal intent.
