I have learned to make a list of everything I think I need before I pack for my cruise. It took me several cruises before I started doing this, though. I forgot to bring aloe vera gel once and got a bad sunburn. Aloe vera on the ship costs about 3 times what it does at Walmart. I also bring an extra pair of reading glasses. I lost a pair on one cruise, and thankfully someone turned them in. (I am lost without my reading glasses.) I love the Las Vegas style shows, but they tend to be very loud, so I am taking ear plugs from now on to help tone down the volume.
