Myth 1 - Day-to-day revenue management functions, like pricing changes, are so sensitive they must be handled by revenue managers themselves.
FALSE - This is a popular misconception; the truth, however, is that the best pricing strategy is one that can react quickly, and often, to subtle market changes, in order to present the best rate to a potential guest at the right time.
Myth 3- Average daily rate (ADR) and occupancy percentage are the best metrics for evaluating the performance of revenue managers or revenue management systems.
FALSE - This was the prevailing wisdom a couple of decades ago, and it persists in some places today. Clearly, these two figures remain important to hotels, but the best measure of a revenue manager's (or an RMS's) efficiency is revenue per available room, or RevPAR.
