@indigofox.dev made a nice map: https://fwa-2025-map.indigofox.dev/
There are three hotels. From west to east they are the Hyatt Regency, the Marriott Marquis, and the Hilton. From the inside, the Regency is brown and square, the Marquis is super tall and has the curvy floors, and the Hilton is blue-ish and has a triangular structure.
The Marquis is flanked on the west side by “Marquis One Tower” and “Marquis Two Tower”. Con stuff doesn’t happen in there. From the inside, they are white marble and have a lot of glass walls.
The location is on a steep slope, so hotel entry/exit points are on different floors on the west and east sides.
There are skybridges connecting all three hotels, but because the skybridges are level, taking a skybridge eastward will take you to a higher floor of the neighboring hotel. The ground floor of the Regency has a wiggly skybridge to “some point in-between Marquis Two and the main Marquis body”; go down the brown hallway and turn right to enter the Marquis from the floor above the main entrance. Two floors below on the east end of the building, you will find a straight skybridge connecting you to the second floor of the Hilton.
The Marquis is particularly difficult to navigate. It doesn’t help that hotels reserve “floor 1” for the first floor of guest rooms, and name the lower floors with random terms.
Note: In the Marquis, there are several rooms called “Event Registration” by the hotel, but FWA does not use them for event registration. Way too small. “Registration Room 1” is just a random tiny room.
There isn’t much wayfinding in the Marquis and it can be difficult to tell what floor you’re on. (If you head to the elevator column, the floor’s name is written in large letters on the wall.)
The main entrance (with the water feature) is on the Lobby Level, floor 3.
Indigo’s map calls this “Courtland” since it’s level with Courtland St.
Sometimes called the “Ballroom Level”.
Indigo’s map calls this “2”
Indigo’s map calls this “Peachtree Ctr” since it’s level with the Peachtree Center public transit station.
Indigo’s map calls this “4”
