You have to be careful with cruisemapper. For one this is an old deck plan, 5D, 6D and many other categories they have listed havent existed for years.
The other thing is that they tend to copy deck plans form the first ship in the class and miss some subtle changes to deck plans.
Also, Royal no longer publishes whether the rooms has pullmans or sofabeds, only occupancy so there is no way for cruisemapper to be accurate on that.
