Universal hosts Halloween Horror Nights, it is a separate hard ticket event ..It is not an event geared for kids.It is an adult-scare event.On days it is going on the Studios close at 5pm to day guests
Have you tried searching on line? I know DTD stopped a few years back. Many places stopped due to cost, safety, liability, etc. If you have a car a lot of the Disney hotels show a family friendly Disney Halloween movie. You don't have to be staying at the hotel.
