The reason the whistle is a siren is because the fog horn does not fit a ship of this era, And without boilers you cant have the ehm Steam whistle. Also the reason for no doors to staircase is that it will ruin the sinking. Also the dark wooden panel room is a lounge. Hope you enjoyed the ship. Also the locked doors in second class is suppost to represent cabins. The only reason for the hallway bed is cheaper prices for pepole who needed to get out of country and stuff like that. Also you forgot to tour the crew cabins, and boiler rooms (Thats fair tho). Also the titanic crew did everything there could during the sinking. Hope you enjoyed the vessel. Also quick fact on the boat you played with. In total the lifeboats seat 120 pepole. Edit: Also if you are intrested i got a steam group.
