The attraction has a narration and is quite unique in many ways to other submarine-type attractions in other Disney parks. After all, the ride vehicles are suspended from an overhead track and does not actually travel underwater. The double pane glass dome windows, contains the water and the bubbles to create the illusion of the submarines diving deep into the ocean.
Guests can see Captain Nemo's Nautilus and the entire fleet of sub 157 "Neptune" hanging from a crane beside the spiral portion of the outdoor queue which is the vehicle-type for the main ride.
The inside queue takes guests past diving gears, Captain Nemo's planning equipment and offices.
Inside "Neptune" (the ride vehicles), guests sit on small benches and each of the three bench seats has a view from its own porthole as guests tour the ships graveyard of "Kraken Reef", and then fall down into "Lucifer's Trench" where the mysteries and dangers of the deep become all to real. There is also a joystick controller at each window to give the guests a chance to maneuver an underwater lamp to illuminate treasure and terror.
