Explanation:
Flight attendants do not usually go home immediately after landing but go to a hotel to rest for the following main reasons:

Continuous and long flight schedules: International flights or long journeys often last many hours, leading to physical and mental fatigue. Flight attendants need to rest before taking the next flight.

Regulated rest time requirements: Airlines and aviation authorities have regulations on minimum rest time between flights to ensure the health and safety of flight attendants as well as passengers. Flight attendants need time off to recover energy.

Flying to other cities or countries: When flight attendants fly to another city or country without returning to their base, they often have to stay temporarily at a hotel before taking another flight.

Specific nature of work: Flight attendants' jobs often require a lot of travel and do not have a fixed schedule. They have to be ready to work in shifts, fly at different times and therefore staying at the hotel makes it more convenient for them to work.

In short, staying at the hotel instead of going home is necessary to ensure health, rest and compliance with aviation safety regulations.
