Adventure v. Navigator

[viajes001]

I was noticing that the rooms are numbered differently on the Navigator of the Seas v. the Adventure of the Seas. I thought both of the ships were supposed to be nearly identical. Is there a difference other than how the rooms are numbered and and the cosmetics/color scheme?

The balcony structure is a bit different. There is more plexiglass on the outside rail of Navigator and Mariner as opposed to the first three Voyager class ships which have more metal. This is due to structural differences in the design. Navigator also has a Chop's restaurant in addition to Portofino's. Adventure has no Chop's Grille. Aside from those issues the differences are more cosmetics.
