I have previously been cruising with NCL (Norwegian Epic) and Royal Caribbean (Adventure of the Seas), so that is what I have to compare with. We always opted for the cheapest possible price/cabin. I was travelling with my wife and two kids (11 and 14).
This was fairly easy. Our luggage (3 out of 4 pieces) arrived at our cabin as expected. My suitcase didn't and the Cabin Steward didn't know anything and suggested it would come later if we wait. In the evening, I called the main desk who informed me that I had to go to the main desk as there was a problem with by suitcase.
