July 4th (and rest of July) hours were updated this morning.
For rest of July, Studios is only extended by half an hour to 9pm, and no Star Wars fireworks are listed. Only one Fantasmic, at 9pm.
MK is extended to 11pm with 2 MSEPs many days, and a few days (Sat/Mon/Weds/Thurs) it seems to have an 8am general opening - including the day I'd booked an 8am BoG breakfast, damn!
On EMH days the MK opens generally at 9am though, so you'll still get in at 8am anyway. Other odd things are some July days (including at least one Saturday) MK still closes at 10pm, but Tuesdays at midnight. Makes no sense, very hard to make plans.
