According to the RCI website, all the cabins on the Serenade have a safe. I've not cruised on this ship but my understanding is that class of vessel has a good amount of room compared to the passenger loading. The ship has both of the extra-fee restaurants - Portofino and Chops. Lots of windows. Pretty fast for a cruise ship too. Serenade can make around 26 knots when she needs to.
