We did it during our trip last April. We were one of the first people in "line" at the rope for the 9a opening. I think we were done w/7DM by about 9:15a.
**Rant warning**
It was a total rat race getting to 7DMT and I didn't like the mayhem with people dashing ahead of others, jockeying for position etc. Even though we were one of the first folks to arrive at rope drop, folks squirmed there way ahead us and showed up out of nowhere via our flank etc. I would not go as far to say there was pushing and shoving but it was awfully close. My 9 y/o was rammed by a stroller... not on purpose but the woman was more concerned about getting to the ride than she was about not running other people over. I refuse to do things like run ahead of others, cut people off, "block" to hold my position. And I insist that my children conduct themselves in the same manner. So by the time we got to the ride there were probably about about 100 people ahead of us (even though we were one of the first in line at RD). I'm really hoping we can get an FP for our next trip. We also booked a pre-park opening ADR at BOG in the hoped of avoiding the mob.
