I've never understood people bothering the stewards when they're working their behinds off getting the cabins ready. I give my bags to a porter, tip well, and get on the ship w/ a fanny pack because I don't want to carry anything. I'm a tall woman, trust me, if my bags were lost I couldn't replace clothing from the ship shops or a port unless it was a cruise to Norway or Iceland.
Be kind. If you don't want to carry your stuff around don't, but don't think it is ok to make the steward's job harder. It isn't.
