You store your suitcases in your cabin, there is usually room in the wardrobe and even under the bed to store the average size suitcaes.
If there is not room in your cabin the steward/stewardess will usually take them and store them elsewhere for you, you may have to leave them open to get them under the bed - which is what we usually do.
It is impossible to put suitcases in wardrobe of any ship I have sailed in, including P&O, Princess, Royal Caribbean, NCL, Celebrity. Have always been able to put 2 large 30" suitcases under the bed with smaller bags and cases inside them.

WE always put our cases under the bed. there's room for two big ones or sometimes a smaller will go into a bigger. alternatively you can give it to your cabin steward to stow for yo.
There is usually always room for your suitcases under the bed, if you are unable to store all your luggage your cabin steward will be happy to take it away and store it for you until you need to pack at the end of your cruise. Hope this helps, enjoy your cruise.
You will find plenty of room under the bed for your cases, my husband and I are also on this cruise....see you there.
