The camera to take with you is the one you best know how to use. If you are going to buy a new camera, do it now, then study every control and get out there and use it, use it, use it, long before your cruise so you are comfortable picking it up and taking good shots is 2nd nature to you.
Stroday's advice (here) is exactly why I'd question renting an unfamiliar brand for a week. It'd probably take me more than a week to adapt to its menu and other intricacies and oddities. I'd rent or buy the camera-system-brand that is the most familiar.
