My family (17 total) and I sailed on the Dawn for the Thanksgiving cruise this year. It was our first cruise with Norwegian, and based on this experience, will be our last. It was an unmitigated disaster from start to finish.
Things got off to a bad start due to the utter failure that occurred during embarkation. I understand this topic has been discussed in other threads, so I won't expound on the subject, but the cruise terminal personnel and the cruise ship personnel continually told different stories of what went wrong. It would have been different if they had been honest, or possibly had even made some sort of "complimentary drink" available, but no....just the lies.
From there , things only got worse. The toilet in our stateroom didn't flush properly for six of the seven days. It was reported to guest services a minimum of three times a day. No apology. No offer to move us to a different cabin. Just a comment that they would get the information to the appropriate department.
Cabin was nothing spectacular, but was as expected for an interior cabin. Biggest issue was the toilet not functioning for six of the seven days.
