MK in Aug. -What opens later than official opening?

[DisneyMom5]

When we were there in Feb. Adventureland and I think ToonTown opened at 10 am when the official park opening was 9 am. Is this the case for Aug.?
How can I find out?
We will be there 8/22-8/27.
Thanks!

While we were there over spring break, Ariel's Grotto opened later. This was also true of Camp MinnieMickey at AK (The character meet and greet).
