It is actually pretty simple how it works. The one time that we did this, we knew what we wanted to do, and showed up 45 minutes before rope drop. We stood behind the rope at the left entrance under the railroad, and the cast members walked our entrance behind one rope, the other entrance had the same escort. Both groups met after the flagpole area and they combined the ropes all the way down Main St. They separated again when it reached the hub and then both groups were able to head through the castle on both sides around the stage, and then the crowd funnels into the standby line to Fairy Tale Hall. It doesn't move very fast, but people still jockey for position as close to the cast members in the front of the lines. If you have a stroller, make sure that you can either hop the curb going up through the castle, or find the no curb area to roll up. We dropped the stroller off at the stroller parking outside the Cinderella water fountains on the left before we got to the line. Even with being near the front at rope drop, we ended up a few rows back due to people jockeying for position and having to navigate the stroller, and ended up having to wait 15-20 minutes in the standby line.
