Whether it's an affair with your spouse or an affair with a louse, Mandalay Bay can take anything that sizzles and make it red hot. The place oozes romance and fantasy. Ask for an executive Jacuzzi suite on an upper level, and you'll get a view of the city that's reason enough to never leave. The Jacuzzi tub seats two, and needs only a sprinkling of scented bubbles to light up the romance in the bathroom. The entire resort can be likened to Fantasy Island. From dining at Aureole, where wine angels ferry your libations, to dancing to congas at Rumjungle or taking in a high-level Strip view from the private Foundation Room, Mandalay Bay has everything. You can even head to Red Square for Stolichnaya vodka martinis or groove to the pulsing beats at House of Blues. If you'd rather go to the beach, consider taking the waves at the sand beach pool surrounded by tiki gods. Whatever you decide to do, this is one affair you'll never forget. Mandalay Bay, 3950, Las Vegas Blvd., 702-632-7777.
