Bonjour,
Je part également en croisière début février. Je trouve ta question justifiée. Je n'avais pas pensé à cet aspect d'une croisière. Ce qui m'a amené à vérifier sur le site internet de ma cie croisière. Va voir sur le site de ta cie il y a surement quelque chose qui en fait allusion dans la foire aux questions. Voici ce que Carnival écrit:

Is There Security on board?

Carnival puts the highest priority on the safety and security of our guests. In order to maintain that environment, we employ a high-profile, onboard uniformed security force. These personnel are onboard to make sure everyone enjoys a safe and happy "Fun Ship" cruise vacation. Carnival Cruise Lines is operating at heightened security levels throughout its fleet and is working closely with law enforcement and federal agencies to ensure the safety of our ships and ports. While we are not permitted to discuss specific elements of our security program so as not to undermine those efforts, we can assure our guests and travel partners that we are at a heightened security status and safety of our guests and crew is of paramount importance.
