Having spent a year and a half in Monorails, I can tell you that we mean Four Bodies. Big, small, doesn't matter. As long as they count on your tax return, they count here too.
I apologise if any host/hostess gets a bit snippy... unfortunetly, a lot of people will try and argue with us, and whatnot. We encounter more problems and situations over the front cab... you really would be surprised at the stuff we have to endure. So, while it's no excuse for snippiness... that's why you may have encountered it. (Not saying that you were arguing... just saying that we get it all the time, so it's a force of habit)
While I'm on the topic... for those of you who might not be aware... to ride in the front with the Pilot on the Express or Epcot beams, simply go up to a Monorail Host/Hostess, and ask them politely if your group may ride in the front. They will either direct you to the person in charge, or let you know if it is available. If it is already taken, you may ask to ride in the next available train. Please note that the front cab is not always available, all strollers must be folded, and has a maximum of four bodies. If your group has more than four, the extras may ride in the regular car. Trips are one way only, as there might be others waiting at the next stop to ride.
For the Resort Monorail, the policy is a little different. Each resort has a train color that is assigned to them for the day. Guests staying at that resort have priority on that color train. You may ask to wait for the resorts train. When the train comes in, you may ride in the front to wherever you want, maximum one round trip. If a different train comes in, and they have room available, you may ride in the front up until that trains resort. When you get there, you may be asked to step to the back, to allow the resort guests to board the front. Please note that the colors do change daily, and sometimes even throughout the day, as circumstances change. Also note that once you are in the back of the train, you may NOT switch to the front, if it becomes available. No exceptions.
Under NO circumstances may anyone ride in the rear cab of the train.
Please note that we have set up these rules based upon thirty years of experience, and have found these current policies to be the most fair to everyone. Pilots are generally VERY STRICT when it comes to the front cab. By allowing one person to break a rule, it creates a huge mess for us later on. That's why we're strict. Loading the front is a special perk that we extend out to our guests, however, it is not a right. We do reserve the right to not load the front cab of any train at any given moment without any notice.
