Conservatory at Bellagio
The atrium inside Bellagio Hotel and Casino transforms five times per year from one over-the-top botanical display to another. A massive team of horticulturists and engineers produce a spectacle of moving parts and thousands of flowers to celebrate the seasons: Spring Celebration, Summer Garden Party, Harvest, Holiday, and Chinese New Year (imagine a giant topiary rat). They spare no expense, filling the 13,000 square foot area with dozens of trees, more than a thousand shrubs, and 10,000 flowering plants. And while few of the best things in Las Vegas are free, this one is, 24 hours a day, seven days a week.
