I'm pretty much hooked on NCL having done my last 5 with them and my upcoming 2.
Yes they do have FOD meetings every night, its posted in the nightly news, and the location is usually the same place around 7 or 8 depending on port days.
Every ship I've gone on is inconsistent on the attendance at the meetings.
I appreciate that NCL does it. I really wish they would choose the location better. The last ship I went on, The Breakaway, it was in Shakers, and I believe was poorly attended as its the bar right in the midst of all the evening activities. On the Escape & the Getaway it was in a smaller venue off to the side and was better attended.
Hoping for a good location on the Bliss in March. Going as a solo traveller, the meet ups are pretty valuable for meeting new friends and having things to do in the evening (not what you think) - talking and people to go to dinner with.
