1. Air quality: Due to the small space of the capsule hotel, ventilation is not easy, which can easily lead to a decrease in air quality, which increases the life safety and health risks of passengers.
2. Privacy issues: Since the capsule hotel is per person, security and privacy issues may occur.
3. Facilities and equipment: The use of capsule hotels is very small, and in order to reduce space, some facilities and equipment are too simplified, which may not meet the needs of travelers.
