Hi - I am staying on Disney property and leaving the Disney bubble for just one day to head over to Universal to visit Harry Potter world. I know all the in and outs of planning a Disney park day but I am totally lost on this one. We'd love to be in the park as early as possible. What time should we plan to be at parking so we can be early for park entry? Like Disney, do they open early? The published opening time is 9:00.
