I was on the New Royal Princess for New Years. It is a refurbished Renaissance ship and will seen quite different from the Emerald as there is no atrium to speak of. Rooms are small, dining is 1st and 2nd seating but there is a nice buffet upstairs and they will serve a quiet dinner every night from a set menu. We took advantage of it quite often as the dining room was busy.
we met the godmother Lorraine Artz and she is a piece of work and you will enjoy her.
Shows are in a very small showroom and the dancers also work during the day as the cruise staff with the trivias and games.
Casino is very small as are most of the public rooms..very intimate if that is what you are looking for.
Let me know if you have any other questions.
