Why do I get an error when traversing the array?

I would like someone to help me how to go through the array, because it does not work for me?

var jsonObject = {

I tried to go through it with this code:

   for (var i=0; i< jsonObject.hoteles.length; i++){
                //Para obtener el objeto de tu lista
                var hotel = jsonObject.hoteles[i];
                document.write(hotel.viaje.origen.name);
        }
