On EMM mornings, the PPO BOG is less of an advantage. They won’t usually let you ride on 7DMT until later than on a day without EMM. We had a PPO breakfast there in a non-EMM day and got 2 rides on mine train and were in line for Peter Pan when the rope drop people got there.
On EMM mornings they hold you in line, so you usually only get 1 ride as the crowds get there. But you will be there ahead of the larger crowd.
