While they are physically connected and part of the same massive resort complex on the Las Vegas Strip, Mandalay Bay and Delano are two distinct hotel brands offering very different atmospheres. Mandalay Bay is a high-energy, tropical-themed mega-resort with over 3,000 rooms, a massive casino, and the famous 11-acre Shark Reef Aquarium and beach club. In contrast, Delano Las Vegas (which has recently undergone a rebranding as the W Las Vegas as of late 2024/2025) is an all-suite, non-gaming, non-smoking tower that prioritizes a sophisticated and "chill" luxury vibe. Guests at the Delano/W Las Vegas tower enjoy their own dedicated lobby, valet, and the exclusive Bathhouse Spa, while still having full access to all the amenities of Mandalay Bay, including the wave pool and various dining options. Essentially, one provides the quintessential, bustling Vegas casino experience, while the other serves as a more refined and quiet sanctuary within that same footprint, allowing travelers to choose the intensity of their stay.
