ACL American Pioneer deck 4 plan (Suites-Bridge-Gym)

The fore-located Navigation Bridge (called "Pilothouse" or "Wheelhouse" on small ships and riverboats) is passenger-accessible. Adjacent to the Pilothouse is the Captain’s Suite and officers' quarters.

The aft Fitness Center is a small Gym equipped with free weights, workout benches, Kinesis One station, treadmills, exercise bikes.

The Vestibule is the ship’s 4-deck-high Atrium (Deck 1 is the lobby level) with an open-floor design. In the Vestibule area are also the two elevators (lifts accessing all decks) and the self-service Guest Laundry room. The Vestibule/Atrium features large windows (portside and starboard on each level), small terraces (on decks 1-2-3-4), as well as a SkyLight cover over Deck 4 (transparent glass roof that allows natural light into the interior).

Deck 4 also houses passenger cabins from 402 to 414, all of which are private balcony staterooms in categories GS-Grand Suite and SS-Sky Suite.

Two Lifts (passenger elevators in the Vestibule/midship) and indoor stairs (midship) interconnect all decks (1 through 5). Aft outdoor staircases interconnect decks 2-3-4-5.
