DHS park hours 2 July

[Trixster]

We arrive on 2 July and there seems to be some discrepancies with the park hours for DHS on that day.

Disney's UK site shows the hours (ignoring the am EMH) as 9 to 7 (some other sites show this time as well), the US site shows 9 to 10 as does WDWmagic.

There isn't a pm EMH that day.

Does anyone know where I can get a definitive answer to this as I am hoping it closes at 10pm so we could catch a few hours after we arrive (subject to being awake!)

Thanks
