I really enjoyed this cruise. It was our 4th (all with NCL). I loved the first two "at sea" days .. no phone, no nothing. As always most staff very friendly and helpful. We had two adjoining staterooms for the 4 of us on deck 13 with balcony. Kids next to us, but that's how it is.
The only thing my in-laws (75 yo) said was, the ship is too large. You have to walk more to come from one side to the other. I was surprised that I never really felt 4000 people as guests (before we sailed on the Pride of America (Hawaii), Jade (Mediterranian) and Alaska they all had about 2000). The option to book excursions, dinners and theater tickets for the shows on the in-room TV system helped there I am sure.
The only thing that should change is the price of internet. Too expensive .. great idea with the iConcierge App ... (use is free, you don't pay for the interenet in this case and as far as i know can talk to other iConcierge members on the ship), but only for iPhone and Android. Would be nice to have it for more brands. We definitely will sail NCL again.
Cabin was a bit small ... the different to other (older) NCL ships was there is not enough storage space. Great to have the in-room TV system to book things on. Don't know if only the Getaway has it or all NCL ships now ...
