If you want to ride it at rope drop be at the front of the crowd with your jogging shoes on. There will be a stampede that will split between 7DMT and Anna and Elsa. In October, we got there for rope drop, but farther back in the crowd and by the time we walked (did not run) down there the line was 70 minutes. Now, we did stop for 1 castle pic as we had a FP+ for later so it was not a rope drop priority for us. We planned to head to things we did not have a FP+ for, and to hit Peter Pan before its line built because we always like to ride it more than once which now is very difficult with FP+ unless you like to stand in line 40 minutes or more. We just checked 7DMT first because on the slim chance the line had not built up yet, we would have gone ahead with that too. We had multiple MK mornings and never saw 7DMT at less than an hour after the initial rope drop sprint.
