torrey:If you haven't noticed already, the SP-350 also has 3 underwater selections in the "scene" mode. I haven't personally tried any of them, but they might come in handy if you never get around to playing with it underwater before your cruise.
The real value of the SP-350 is the "My Modes" in setup. Since you should shoot everything in manual mode and not program mode or auto the My Modes can be set up to change all the camera settings to the default "starting points" for wide angle and macro.
The basic settings to start with if you have a strobe would be .. ISO-100, F-8, 1/250 for Macro and that would drop down a couple F stops and 1/125 or 1/100 for wide angle depending on how dark the water is. There is also a setting in there (check the manual) on setting the LCD view to not show "live" view. If you don't change this, the view finder will be too dark to see anything under water. You can try this out on land and change the setting and see the difference.
With the My Modes, it will make life easy because you can change everything on the camera with a push of a button.
Hope this helps
