Answer and Explanation:
Water has a property that allows it to need either a very high temperature to heat or a very low temperature to cool, unlike the land that does not need such extreme values to change its temperature. This ability of water to need a lot of energy to change temperature ends up being transmitted to regions close to large volumes of water.
In that case, bathers will be subjected to a higher and hotter temperature if they are close to the water than if they are in the hotel.
