Everyone gets a trick or treat bag when you enter the park. The trick or treat stations are marked on the map they give you, but in the park they are marked clearly with large orange balloons floating over them. Last year the lines moved really fast in all sections but fantsy land. The candy was good name brand candy, it made for a good evening snack for the rest of our trip.
Make sure you don't just trick or treat take in all the night has to offer.
Have a great time!!!
