Lunch is available as soon as you board. They don't start boarding till the food is ready. Your choices are Parrot Cay and Topsiders (same food, different atmosphere), any of the "fast food" outlets on deck 9, and after 1:30 you can order room service. NOTE there is NO food available anywhere from 3:30 - 4:30 as the crew starts preparing for the safety drill at 3:30. Food opens up again after the drill.
Packing lists--some people are crazy! If you don't know what something is for, don't bring it! Bungee cords to keep doors open--your stateroom host will supply door stops that go at the top of the door to do this if you have connecting staterooms. Night lights--as above, light on, bathroom door closed makes a great night light. I do like a lighted clock when I have an inside room as I have little idea whether it's day or night, but setting the TV to the "view from the bridge" channel and turning the sound off will give you the same thing--the view from the bridge is total blackness when it is dark out! I've never figured out why I'm supposed to bring duct tape...which seems to have been re-named duck tape. Yes, I know it has all sorts of uses at home, but if my closet door needs repairing, etc. on the ship my stateroom host will deal with it. If I need to repair a tear in my luggage, he'll even provide me with a piece of tape for that.
I'd need 10 suitcases to bring all the stuff on some packing lists! Read them, but think about yourself and what YOU will use.
I do find the shoe hanger to be useful. We put it on the bathroom door (outside) to hold all sorts of toiletries, sunscreen, cameras, etc....stuff that you need to put somewhere but that might need to be used by more than one person. It's a bigger deal with the single bathroom than the split simply because you have more room in the split.
Ice cream cones--some people are not happy that these are sometimes not available at the ice cream station on deck 9. Over the years,
DCL has varied as to whether there are both cones and cups available or just cups. There are always cones at Castaway, and CMs can get you cones if you ask. OH, but they are the coned with the pointy bottom and some people's little darlings only like cones with the flat bottoms. You know, if you feel the need to bring ice cream cones onto a Disney ship, go for it. I don't have that much space in my luggage or my head! I'd tell my kid to eat it from the cup or order a Mickey Bar!
