Having just disembarked from a Norwegian cruise on Sky Princess, need to share some points: Standard balcony cabins quite small compared to other lines (completed 32 cruises) so can compare. Shower curtain on a new ship seems to be a step back in time. Food all good apart from main dining room.
Main dining reservation and organisation shambolic with non reserved guests walking in on one side while booked guests in long queue on other side! The service in main dining rooms were; at best, eratic. Some areas efficient while others were really poor no consistency! Still laying table as you are seated made it feel like a cafe rather than entering a restaurant. Staff really need training. Just be aware Princess that the main restaurants should not be second rate to other chargeable venues. All restaurant services should be equally good.
Cloudy cool sea day makes the centre of ship overcrowded with nowhere to sit and not enough waiters. That’s not to say, however, that they didn’t work hard, just not enough in the correct position.
