deerskull Cruise Review on Norwegian Star on Dec 14, 2018

Thanks for the tip

Despite endless warnings about what can and cannot be flushed down a vacuum toilet, many passengers just don't get it. They treat the toilet like a garbage disposal. Once it stops up, sewage and smells escape along corridors and into cabins until the engineers can correct the problem. On a large ship this typically occurs 20 or more times per day, all over the ship. A single toilet stoppage can have negative effects on as many as 60 additional cabins.
