Having cruised previously with P&O, NCL, and even Carnival, we had high expectation of RCS after reading so many good reviews of the line.
While some aspects were very good there were a combination of things that only served to confirm that we will think twice about booking again, though we tend to book on itinerary and date and not through blinkered loyalty to any line.
Taken in isolation the issues might not be significant, but grouped together they took the shine off the cruise:-
Very good balcony size. Standard room. Cabins above and below so quiet. Midships so same distance to fore and aft stairs. Good shower power. Shampoo only, no shower gel.
Good organisation and nice to laze on the beach. Free chairs, lunch and drinks package is good on land.
