I would say that most people follow the people in front of them!
When we went I think we went to the left, following the people in front of them.
Of course we did early entry, got to WWoHP, went to the FJ line, got into the greenhouse and then FIRE ALARM. We then had to leave and we did other stuff. When it opened back up, we were assembling our family and one of the workers asked if we were waiting for somebody and I said yes because of the fire drill and he told us to let the person at the lines know he sent us and then we got to go in the quick way. But later in the vacation we went back in because half of the fun is the line queueing.
