Quiet ships [don't like the Pinnacle class - the Lido pool area background music is much too loud - it's like they are trying to make up for having a double deck]. Itineraries, the crew, FLL/PEV is a non-airplane destination for me - train instead.
Rooms ready on embarkation and freedom to disembark when you are really ready to leave. And again the crew and the service.
I've been on one other line since 2015 [RCI] and it seemed like the loudspeakers were never switched off - and too many 'toys' I have no use for - and this was one of their smaller ships.
