Unless it's 'bigger is better,' there is no real theme at the Strip's most staid megaresort, with a football-field-sized casino overhung by twinkling chandeliers and overstuffed blue velvet chairs. But Bally's biggest attraction isn't about gaming: Jubilee! is one of Vegas' long-running showgirl extravaganzas. Just how big is Jubilee!, you ask? More than 1000 costumes are worn during the $50-million show; almost 70 stagehands are required to operate the stage, sets, lights and sound equipment; and no less than 4200lbs of dry ice is used each week to create the production's fog effects.
