All in all, this a great ship with lots to do. For the most part they've done a great job spreading out the crowds, however, there are few areas where the huge number of passengers becomes a big problem. I will detail them below.
PROS: The "Central Park" neighborhood is breathtaking. It really feels quiet and intimate. You completely forget you are in the middle of a huge ship surrounded by hundreds of rooms looking down on you. It's pretty amazing how this is accomplished.
-Very quick bar service. Maybe it's the sheer number of bars, but I barely waited for drinks the entire cruise. This is in stark contrast to previous experience on other ships.
BATHROOM: The water was insanely hot some days. Other than that, the bathroom is typical of what you'd expect on a cruise ship. However, this one is laid out slightly difference so there was actually leg room in front of the toilet.
BALCONY: When you look at the ship from photos, you see a wall of balconies. However, when you are actually on the ship, they are surprisingly private (the oceanview ones, that is. The ones facing inside the ship are not private)
