Honestly I think a lot of people overestimate the wait time for the Monorails/boats. For example, when the Express Monorail ramp is packed full of people all the way down to the very bottom of the ramp, that is about a 6 minute wait until you are about to get on a train (assuming trains are running the regular 2-3 minute intervals which they usually are at the exit.)
Even if the entire ramp is full and we have most of our queue full, that wait is about 20 minutes tops. It's so funny to me to hear Guest's exit the park and see the line and say with all sincerity that they honestly believe the line is going to take hours. When I tell them it is 15-20 minutes they don't believe me. :shrug: Meh, don't trust me I just work here. (Not saying that to anyone on this thread specifically, but that's what runs through my head when people ask me a question and think they know the answer better than me.)
Bottom line is, the line for the Monorails is almost never as long of a wait as it appears. Moving 350 people every 3 minutes clears them out pretty quick! Normally if I am doing fireworks exit Audience Control, the finale is roughly 12 minutes after the hour, and we are usually tearing down the queue at about 45 after the hour, meaning from beginning to end the rush is only about 30 minutes.
Obviously if the Monorails aren't running, that information isn't very helpful

But just for general reference when you all are there next and the Monorails are (hopefully) running.
