Was there on May 29th for park opening. We were just outside the tunnel under the train station so while not up front, not near the middle or back. We walked down Main Street in a very large group but with no issues from seeing where we were stepping. Our only issue was the mother screaming at her husband and child already while wildly pushing her stroller. At the Hub the rope dropped and guests headed to each land including many going through the castle to the Frozen girls. We went by the Rose Garden and Teacups to get in line for the mine train. Within 20 minutes the line for Anna & Elsa was 300 minutes so I guess most were heading there. After hearing horror stories we were very pleased and comfortable with the procedure.
Sending everyone through the castle makes no sense whatsoever when many who were there were going elsewhere.
