We have been on 15 cruises previously, mostly with RRC or Celebrity.
We wanted and liked the 2 or 3 days at sea on both ends of the cruise.
Its really relaxing to "book-end" your itinerary with days at sea.
Our cabin was about 10% larger than other cruise cabins we remember.
There was significantly more storage as well.
And the closets had 25 hangers - not the usual 5 to 10. Amazing!
Definitely a step up from other RCC ships.
