Is there rope drop on MM days?
On days where official park opening is 8AM, MM would be 7AM. There is no rope drop at 7, but there is a rope drop at 8 at the entrance to Frontierland and Adventureland. Also nobody is let into the park until 7AM. Non-MM guests might be allowed in any time between 7:30 and 8AM.
On days where official park opening is 10AM, MM would be 9AM. I believe that there is a rope drop at 9 at Fantasyland and Tomorrowland. Then another at 10AM for Adventureland and Frontierland. Nobody is let into the park until 9AM. Non-MM guests might be allowed in any time between 9:30 and 10AM.
On days where official park opening is anything else, opening procedures may change depending on crowd size.
