my wife and I are the type that clean the cabin from stem to stern as soon as we get in. We pack Clorox wipes, Lysol spray, and rubber gloves in our carry on luggage. We clean everything before we unpack. And I am glad we do.
Our steward was responsible for 28 cabins. 28 cabins, 2x per day. That's pretty hard to do. If you've ever watched Hotel Impossible on the Travel Channel, you'd understand.
Remember, a ship is a hotel at sea. And it gets real dirty.
Don't forget the TV remote while you're cleaning.
