Vegas has a culture of change. And especially with visitor numbers picking up, there are pretty frequent and swift changes taking place currently. In every industry, competition can be intensified by well-made changes. But for Vegas this means that these properties will be throwing hundreds of millions of dollars sometimes into changes to make their property more competitive...and frequently. The bottom-line price-tag for these changes/upgrades are often widely publicized. In the 90s and early 2000s, how much money was being poured into "change"? What are the figures now? What is the overall financial climate then and now? What were the non-financial costs?
