My teenage daughter and I (Mom), took this cruise in February 2011. Our third cruise with NCL, but first without the guys in our lives!
The Dawn isn't as run down as many on this forum have said. We found it to be clean and comfortable. Our oceanview stateroom was a decent size. The TV in it was old, but who goes on a cruise to watch TV? The most worn out areas I found were the public washrooms - easily avoided.
What we like about NCL is eating when and with whoever we want. Also we like not having to dress up if we don't feel like it.
