On our first 4 cruises, we booked Verandah rooms.
But our last cruise, we booked Cat 11 (they were steeply discounted).
What we missed most was the extra storage space.
So I would suggest trying for at least a "Deluxe" stateroom (Cat. 10 or better).
If you are trying to save money and going with a Cat. 11, then I would suggest the over-the-door shoe holder others have recomended to help make up for the limited storage space.
