Hotels prefer percale sheets over sateen. For one, sateen sheets feature a complicated weave pattern that is not as strong as the percale one. Percale on the other hand flaunts a one-over-one-under traditional weave pattern the strength of which makes the resulting sheets highly durable and way cooler than sateen sheets.
Percale sheets with their crisp texture, are breathable and allow air to pass through. This generally means guests can sleep cool, without sweating at night and the sheets can therefore work fine while requiring minimum maintenance.
The percale sheets are also more affordable than sateen ones. Sateen has a rather silky texture to it and is more prone to pilling than percale, which is why it is less preferred by luxury hotels.
