As you mention being in an inside cabin, let me bounce a question off of you that I have already asked on the general MSC board.
Are you able to store your luggage underneath the bed?
Given what seems to be an astonishingly small area for storage that is provided, it seems like using our suitcases as daily storage areas might be the way to solve the problem.
As you can probably tell, this will be our first time in a YCI cabin.
