Which rides open right at opening at the Studios?

[christophfam]

We're staying with family on our next trip so I thought I'd better plan a bit and get to the Studios at opening. I remember from off site trips in the past that not everything is open right at 9AM, but can't remember what is and isn't. I actually remember it being a pain. Can anyone tell me what opens right at 9AM and then around what time the rest of the rides start opening up?

Thanks!
