I just got off of the Dawn 3 days ago. My twin brother and I cruise together and had a great time. The cruise went from New Orleans and stopped at Cozumel, Belize City, Roatan and Costa Maya.
The ship was extremely clean and ready to go. Luggage delivery took quite a while but they deal with thousands of bags so that is understandable. We couldn't wait for our dinner at Le Bistro and were not disappointed! This is easily my favorite restaurant on most of the Norwegian ships. We went to Cagney's the second night and the steaks were way undercooked and food was generally lackluster. We mentioned it and Max, the manager, came over to address it and invited us back later that week to make up for it. We returned Thursday night and it was wonderful! (Bison was great as was Max - thank you!) The Brazilian restaurant was good and the Osso Bucco at the Italian restaurant was amazing.
The drinks were good. Mojitos were hit and miss but after a few of them, who cares! :)
The cabin was as expected. Not too small and ample storage. No issues.
