"I don't know if the guest's life is in danger. But he has a room with a balcony and we're a little afraid that he might do something life-threatening," said the hotel's front desk manager in a second call.
Payne's room was on the third floor and had a balcony about 14m (45ft) above an interior courtyard.
It is thought he fell from the balcony at about 17:07 local time.
