First I just want to say, I don't understand all of these negative reviews. This was literally the BEST cruise experience I've ever had, and I will definitely be sailing with Norwegian again. I've been on 3 Royal Caribbean cruises before this (2 were spectacular, 1 was horrendous), but I've never had as much fun as I did on the Norwegian Escape.
I think the kind of people posting bad reviews here have either A) never been on a cruise so have ridiculous expectations of what life is like on a boat OR B) they are the kind of people you can NEVER please. You give them a pile of diamonds and they'll still say They Ain't Shiny Enough.
Positives:
The bathroom is to die for. Enough said.
Beautiful port, but not much to do. I only went off the ship for about an hour then came back to take advantage of the fact that no one was on board (yay pool to myself!)
The Miami port was a bit crowded and not the prettiest place to be, but overall it was efficient.
