I leave my kids (6 and 8) in hotel rooms alone all the time in the philippines (and have been doing it since they were 5 and 7). It's usually for an hour while I run errands and they just play games on their ipads. They know not to touch windows/curtains/blinds, to go outside in case of fire alarm, and to go to the front desk in case of emergency. They know how to call Mr. Bee on Viber, and the hotel has my phone number (though they see me leaving the kids as perfectly normal).
It is legal here and I was home alone waaaaay earlier than they were. Of course I could never do this in the US or I'd be arrested!
