Final answer:
The factors causing variations in water usage for similar-sized hotels include occupancy rates, local climate, seasonal trends, water conservation measures, plumbing efficiency, and guest behavior, with all options being correct. Option D is correct.
Step-by-step explanation:
The factors that could cause large variations in water usage for hotels of similar size include occupancy rates, local climate, seasonal trends, water conservation measures, plumbing system efficiency, and guest behavior. Therefore, the correct answer is d) All of the above.
High occupancy rates lead to increased water usage. The local climate and seasonal trends can influence the amount of water needed for heating or cooling and can affect the frequency of water-based recreational activities available at the hotel. Water conservation measures implemented by the hotel can significantly reduce water usage.
The efficiency of the plumbing system also plays a crucial role in minimizing water wastage. Lastly, the behavior of hotel guests, such as their showering habits or preference for daily linen changes, can greatly affect the overall water consumption.
