First cruise? Leave it along with the cell phone at home. Get a go phone for emergencies and leave the electronic leashes behind man. There's so much to do that when you get back to the room you'll wonder why you brought it. Especially if you are going to the islands. Even sitting on a deck chair watching the waves beats looking at a pc screen especially while drinking smoothies. The cabin maids won't really mess with it most likely though. Just food for thouht. Have fun on your trip either way! Cruises are awsome.
AMEN.
When my wife and I went on our honeymoon
http://www.psvresort.com/ we brought the laptop, but that was it. Cell phones got buried at the bottom of the suitcase for an emergency.
Since we own a DJ business, all of our music is on the laptop(s). Once on the island, I set up a playlist, put the speakers on a shelf, closed the laptop (after setting it to do nothing when the lid was closed) and covered the damn thing with a towel. Basically, it spent 5 days being a very expensive jukebox.
If you can't find something to do aboard ship to entertain you and occupy your time w/o needing the computer, then you don't need a vacation that badly, yet.
