So, I noticed today that the park hours changed again for next month to bring both parks the same.
For the longest time, IoA was opening at 8am and closing at 9pm towards the end of June. Now starting on the 19th, both parks share the same opening and closing times with the exception of two days. On the 21st IoA closes an hour later at 10pm with US closing at 9pm. Then on the 24th IoA closes an hour early at 9pm with US staying open till 10pm. From the June 25th through the 30th, both parks share the same times of 9am and 10pm.
Two things stick out. The first is from June 14th through the 18th, US closes at 8pm which is an hour early compared most of the month. Could this be for press and media, family and friends, employees, and the cast and crew of both the films and the land to come out and enjoy the area before they unleash it to the world? The other odd thing is the July park hours have not been touched yet. July still has IoA opening an hour early and closing an hour early compared to US. I have a feeling that July will be getting updated to the 9am-10pm schedule soon. It solves their problem of what to do with HE when both parks are not open.
