What unused themes are left on the Las Vegas Strip? How about Miami's South Beach? That's the plan for an announced $165 million renovation and redesign of the Tropicana. The project is the most ambitious proposed for Las Vegas since the economy cooled the city's frantic construction pace.

It will result in remodeled rooms and meeting space, new restaurants, and an overall new look for one of the Strip's oldest resorts. While some of the new rooms will be ready within a month, the entire makeover is expected to take about a year to complete.
