I just got back from my first cruise. I made a list of all the things that MUST be taken, gathered from various cruise websites. I ended up taking LOTS of UNNECESSARY items. Here's the ones I really used: a multi-plug strip for recharging cameras, phones, etc; a plastic toothbrush holder with suction cups that stuck to the mirror; a yellow highlighter for marking the things we wanted to do each day; and the MOST useful--the soft-side, roll-on cooler. Seriously, I could have taken one full suitcase less if I had left most of the unnecessary stuff at home.
