I apologize for the length, but it's worth the read if you are seriously considering this ship.
I am 17 years old and this was my ninth family cruise, first on NCL. We cruised for 7 days from NY to Bermuda. To start off, I traveled with 21 people as my grandmother spent over $25k just to be treated RUDELY by the absolutely abhorrent staff on this ship. I highly doubt many teens take the time to write a review on these sites, but the experience was so horrid that I had to.
First of all, this ship is VERY crowded. There are two pools, both small, and one is only accessible to adults. God forbid a child would step in the pool to say "hi" to his/her mom or else the security watching like a hawk would YELL and SCREAM at them to get out. This happened to my nine year old brother and five year old cousin. Everywhere else I just felt like I had to squeeze through crowds of people and the hallways- don't even get me started. My aunt has infant twins and brought along a wide double stroller. It JUST fit in the hallway, but if housekeeping had their cart out, it was nearly impossible for her to get to her cabin. Not that there is much to be done about that, it was still a pain.
Disembarkation went very quickly and efficiently.
