We chose the NCL Bliss, because it is big and new and will bring us to our long planned destination -- South Caribbean. Unfortunately, captain announced after get onboard that we had to skip Puerto Rico due to waves (each passenger got $16 refund.)
The previously NCL advertised Free bar, Free shore excursions, Free WIFI, Free specialty dining were not available at all. (You probably have to pay more to upgrade your cabins.)
Forgot to bring books to read? Playing ping pong was then a major activity for many of us to kill time. (New ship has no basket ball court.) It was a really disappointment. The indoor game has been still placed on an almost open area, though mostly covered ceiling. Wind and rain blowing through the open glass panels and balls flying in all directions or ditches. You had to chase balls towards underneath many beach chairs. The glaring sun beans made players put sun glasses to play in the afternoon. The dim light made playing almost impossible after 5:00pm. The worst scenario was that ping pong balls kept shooting out of ship and fell into the sea. Shame on NCL to pollute the sea!
Cabin cleaning was just basic. We put on "Do not disturb" sign for more than half of the journey. Of course we still had to pay the $15/day.
