Yes, if the pattern holds, Friday Aug 2nd should the be hours update you need. But, I'm not sure if July 24th will yield an update to hours. I think they need to have hours out to Aug 13th on July 24th -- people who check in on July 31st for a 14 night stay should be able to book through Aug 13th.
I am most interested in MK hours on
MNSSHP days ... I think MK opens at 8am on MNSSHP days, but last year I didn't go to early entry at MK on my party dates, so I can't tell from my photos.
I'm also interested in AK hours. I really miss evening hours at AK. Some of my favorite disney memories are from AK at night. Although I think there is <1% chance of evening hours at AK in August.
