Great ship, good choice, hope you all enjoy. There are in room safes in each room. There is no charge for using them and I suggest you do. Once aboard ship you have little reason to carry money, or ID and should also lock away jewelry and credit cards.
I forget whether they are accessable by a code you set or by swiping any magneticly coded card such as your room card or credit card. Either way there is personalized access.
Enjoy your cruise and be sure to let us know your impressions when you return.
