So sorry you had a bad cruise on the Imagination. Something to keep in mind (not that it is an excuse) is the Imagination was built in 1995 and refitted in 2007 so the plumbing is old which may explain the septic type odor. Again, it's not an excuse and the Guest Services desk should have addressed it IMMEDIATELY!! As for the painting, vessels are maintained in port for safety of the crew especially when it comes to painting. This is no excuse but keep in mind it has to be done and the ship usually only has a 3 or 4 hour window for turn around (getting passengers disembarked and boarding new passengers). I note you reached out to Carnival and got a basic response. What I usually recommend passengers do is write a letter to their corporate. Mail it and you usually get a response within 2 - 3 months but you can be assured that someone ACTUALLY read your letter. In return the cruise line will respond with some type of amenity (discount and/or On board credit) towards another cruise with them. Email's are directed to a help type desk and you will not get the attention you deserve. I have been on 5 Carnival cruises and I have had many memorable times. PLEASE, do not let this be a decision maker regarding cruises in the future. Maybe a bit more research prior to booking like reading past passenger reviews will help you make a better decision. Best of luck and hope to see you on board ;)
