Sometimes if you do point it out. They would be quick to fix the issues. Possibly they are waiting for the contractor from dry dock to come aboard and see these issues for possible work guarantees.I didn't because I didn't see anything that seem life threatening or be a health hazard but let's just say that it makes Carnival look like an even better value now in our eyes. We did comment about it on the comment card, though.
As for the host, the room was cleaned every day... I haven't lessened the gratuity because it's not something I do but I did not write "excellent" on my card and did not mention his name on the card when we named the CMs who gave us the best service.
I would not compare this time to Carnival as this is not the norm for DCL. It is however the norm for Carnival.
