Having done five cruises on NCL since the restart, we definitely do see the recent changes. Food quality/choices at the buffet and nighttime entertainment leading the way.
We tried to place an early room service order for one morning for breakfast and was told the earliest it can be delivered is at 6:30 a.m. which was too late for us. The MDR was opening at 8:00 a.m., buffet at 7:00 a.m. and the Local at 6:00 a.m. I do not remember in all of our previous cruises as not having at least two options.
We also wished you were still able to reserve the comedy shows as you used to be able to. On the Encore recently, we had to get to the venue way too early just to get the last two seats.
As I mentioned in another thread, while we still love NCL, we love NCL a little less now.
