Resorts catering to the high-end market are offering unique and opulent swimming pools to help attract guests. The pools often cost millions to build and take on Olympic proportions.

Fueled by unprecedented competition for guests, hotels are pouring millions of dollars into pools—not bathtub-size afterthoughts, but sybaritic, resort-style pool complexes and waterside amenities. These new ersatz beach clubs go beyond the well-stocked cabana to add acres of real estate, residential design and furniture, gadgets, and increased staffing.

The Tuscan-villa pool at the Bellagio (shown above) in Las Vegas features misting fans and fountains. Pools at the Bellagio are kept at different temperatures so sensitive swimmers can find the perfect fit. At the Burj Al Arab resort in Dubai (shown below) the pools -- one for men and one for women -- feature large windows offering panoramic views of the Persian gulf.
