The Grand Lobby is the first floor of The Last Resort in Luigi's Mansion 3. It is the first area to be explored in the game. At the start of the game, the lobby is bright, colorful, and lit up, with presents and staff everywhere. There are also pictures hanging from the ceiling of Luigi, Mario, Princess Peach, and Toad. Most parts of the Grand Lobby are inaccessible at this time, including the elevator and the stairs to the second floor. Luigi must talk to the Steward at the front desk to check in. Hellen Gravely then appears and escorts them up to their rooms on the fifth floor, the RIP Suites.
After obtaining the Poltergust G-00 from the Garage, Luigi must return to the Grand Lobby.
The next time the Grand Lobby is visited, it undergoes major changes. It is much darker and less colorful. There are jack o' lanterns scattered across the floor, and the swan ice sculptures are now gargoyles. The pictures above now have X's over them. Luigi discovers two Goobs, barring up the front door to prevent their hostages from leaving the hotel, and defeats them. Polterpup then leads him up to the Mezzanine, where they find Professor E. Gadd trapped in a painting.
The Grand Lobby is the only floor of the hotel with no boss ghosts.

|Found above the desk to the left of the lobby. Luigi must walk up the staircase to the left and push the carpet with the vacuum to reveal a grate in the floor. Gooigi must then drop through the grate and dislodge the gem with a Burst, allowing Luigi to collect it.|
|Stuck in the plant to the right of the elevator. Luigi must use the Suction Shot to destroy the plant, then collect the gem.|
|Hidden behind the front desk. To access the area behind, the player must use a Burst to open the desk gate. Luigi must flash the safe with the Strobulb to reveal the gem.|
|Hidden in the chandelier. Luigi and Gooigi must stand on the pressure plates to the sides of it to lower the chandelier, then aim up and vacuum it to reveal several coins and the yellow gem.|
