Yes, that is how I saw them in the comedy club and the casino. I always carry a bag on with medical supplies and the first cruise I just lugged it around because I didn’t know this service existed. The second cruise, on the Prima, we saw the cabin stewards and asked if we could leave the bag in our cabin. She said that was fine and we put them in the closet. That was probably less secure than the baggage drop areas but I didn’t see that until later. Now that I know this service exists I will use it going forward.
