Review of MS Rhein Prinzessin deck 1 (Neptune)
Cruise cabins from 100 to 115, all of which are Outside Twin Staterooms with Porthole Window (non-opening, located near the ceiling) in categories A-midship and B-aft.
Aft are located ship's engine room and crew-only areas.
One staircase (forward) connects all decks. One lift (forward) connects decks Saturn and Orion.
