On our last visit, it seemed to start working about 15 minutes before the other park opened, with the line queuing up a little earlier than that. It's a nice way to get a head-start on the other Harry Potter area before everyone else gets there.We will be at Universal 13th and 14th August and both parks are showing as early entry at 8.00 am. Will the Hogwarts Express be running during Early Entry or will I have to wait till 9.00 to ride?
To follow up on the question: What's the quickest way to get from early entry HP area to the other park's HP area? Is it the train? First trip coming up in late September and both our littlest kids are big HP fans. Thanks in advance.
