I would try, but given the circumstances you may not be able to, and that's fine too. You can get so much accomplished being at the park a half hour (or even 10-15 minutes) before it opens. Especially if you have FP for the longer wait attractions later (things like FOP, SDD, 7D).
We went to HS for AM EMH MLK weekend. We were there about 20 minutes before it opened, but they were letting people in and holding at ropes from there. They started walking us down 5 to 10 minutes early. We rode RNRC, ToT, and were getting a picture taken at 8:24. After the picture we glanced down at RNRC, and it was listed at 45 minutes. That was around 20 minutes after we got in line for it. We had many other good morning experiences that week, but that one really stuck out to me.
