The Decks Were Always Kept In Pristine Shape
There were four decks from A Deck to D Deck that were above water and could be enjoyed by the passengers. Every deck was kept in tip-top condition by the crew no matter which class inhabited them. This was because each deck was partitioned off, rather than having full separate decks for each class.
For your average third-class passenger, the attention to detail on everything, including your lower-class deck, probably made the Titanic voyage feel like a dream.
