Norwegian Cruise Lines should sell their ship, The Epic. I've never been on her, but she was a huge mistake, and this is how you can tell.
The Epic was built as an Epic Class ship. 155,873 GRT / 4100 pax cap.
The Breakaway Class includes the Breakaway & the Getaway. Each is roughly 146,000GRT and just under 4000 pax. Both are a bit smaller than the Epic Here comes the odd part:
2 ships are currently classified as Breakaway Plus Class ; the Escape & the Bliss ( coming in 2018 ). Each is over 160,00 GRT, and each carries roughly 4000 passengers. Notice they are both larger than the Epic, but not called Epic Plus.
There is no point to all of this, other than to point out NCL may have realized their error, and by classifying ships as Breakaway Plus they are trying to separate themselves from a huge monstrosity called the Epic.
Admittedly, if you read this, I have wasted your time, and that's 5 minutes you'll never get back. Sorry.
