Reaching the pinnacle of the Last Resort hotel brings players to the glamorous Master Suite, a floor packed with intricate puzzles and hidden secrets. Collecting all six specialized gems on this final level requires a masterful combination of Luigi's entire toolset and Gooigi's cooperative puzzle-solving skills. Navigating this grand penthouse effectively ensures you can achieve complete completion and unlock the ultimate rewards hidden within the game's final stage.
The Lounge and Bedroom Hidden Gems
The journey begins in the main lounge area where clever exploration reveals the initial hidden treasures. To uncover the first gem, players must look for a concealed path hidden behind the decorative architecture in the grand hallway. Utilizing the Suction Shot on the nearby environment reveals a mechanical switch that releases the shimmering collectible from its secure housing.
Moving deeper into the master bedroom requires careful observation of the structural layout and interactive objects. A specific rotating wall puzzle can be solved by manipulating the local electrical switches with your flashlight. Once the correct sequence is input, a secret compartment opens up to grant you the next colorful prize for your collection.
Bathroom and Library Environmental Puzzles
The luxurious bathroom contains complex pipe networks that are perfectly suited for Gooigi's unique traversal abilities. Send your slimy duplicate through the drain system beneath the floorboards to access a restricted chamber. By shutting off the main water valves, you can safely guide him to intercept another valuable gem floating inside the bathtub area.
The towering library section presents a vertical challenge that tests your spatial awareness and platforming timing. Players need to use the powerful burst ability to clear away loose papers and debris blocking the hidden floor grates. Revealing these passages allows you to navigate the upper rafters where a hidden safe holds the next essential collectible.
The Screening Room and Final Showdown Area
The grand screening room features a massive display screen that holds the key to one of the most clever puzzles on the floor. Players must interact with the projector equipment to shift the shadows in the room and reveal a hidden doorway. Stepping behind the main stage setup allows you to vacuum up the fifth gem hidden within a network of rafters.
The final collectible is situated near the entrance of the main throne room where the ultimate boss encounter takes place. Before initiating the battle, look closely at the decorative structural pillars lining the left side of the grand hallway. Using your Dark-Light device on the empty space materializes a hidden chest containing the final gem needed to complete the floor map.
