I had no idea that the hours changed so much. I will keep that in mind for the fall or winter trip. Is that what causes the change?
The hours change based on crowd levels, holidays, weekends, peak seasons and special events. For example, during the busy summer months, the park often opens early with “Extra Magic Hours” and stays open past midnight. đŸ™‚
