This should really come as no surprise to anyone:
The global cruise industry announced a new emergency drill policy requiring mandatory muster for embarking passengers prior to departure from port. The new policy follows the industry’s announcement on January 27 of a Cruise Industry Operational Safety Review in response to the Concordia incident and as part of the industry’s continuous efforts to review and improve safety measures. The Cruise Lines International Association, European Cruise Council, and the Passenger Shipping Association put forward the new policy with the support of their member cruise lines.
