Understand we have over 13 cruises on Carnival, and 3 on Royal Carribean. Had sailed NCL once about 15 years ago. Just went on my second and LAST NCL cruise.
Here are the facts:
Cabins are smaller on NCL
Smaller than carnival balconies. Door rattled when the wind blew or the ship went fast. Kept us up for 3 nights. Stools didn't want to flush...took repeated tries and was scary.
