Which of the following metrics would be essential for comparing revenue performance across different hotels?

The RevPAR index, or Revenue per Available Room index, is crucial for comparing revenue performance across different hotels because it provides a standardized measure that accounts for variations in pricing and occupancy across the properties being compared. By focusing on revenue earned per available room rather than just total revenue or occupancy rates, the RevPAR index allows for a more nuanced analysis of how effectively hotels are generating income relative to their capacity.

This metric is particularly valuable because it incorporates both occupancy and average daily rates (ADR) into its calculation, providing a comprehensive picture of a hotel's financial performance. When evaluating multiple hotels, the RevPAR index helps identify which properties are outperforming others, regardless of size or market segment, making it essential for revenue management and strategic decision-making in the hospitality industry.

Other metrics mentioned, while relevant in specific contexts, do not offer the same level of comparative insight across various hotels. For example, occupancy spread may focus solely on occupancy differences without accounting for pricing strategies, seasonal occupancy rates are limited to specific time frames, and facility amenities do not directly correlate with financial performance.
