A futuristic floating hotel anchored securely to the ocean floor, designed with sleek, ultramodern architecture that includes large glass walls and elegant curves. The hotel floats above the water, with luxurious suites offering panoramic ocean views. Below the surface, a fully glass-walled restaurant is submerged underwater, allowing diners to watch vibrant marine life like tropical fish, coral formations, and other sea creatures passing by in their natural habitat. Display the hotel from a side view, capturing both the above-water structure and the underwater restaurant in a calm, deep blue ocean environment. Sunlight filters from above, illuminating the water and casting gentle light on the marine life around the restaurant.”
