As the operator of the machine that can cause the harm, you have to accept the most responsibility. Even if that means you pull aside and wait until the crowd thins out.
As the user, you accept knowldge that there are idiots present, but you have to give right of way, all the time, every time. So you have to to give extra room, you have to go slow, you might even have to leave early or stay later, but to put yourself in the middle of that much pedestrian traffic is just selfish. You have options, if you choose not to use them you should not place blame on anyone else nor call them an idiot.
The place is filled with kids of all ages and people who are exhausted with dozens of things on their mind and your vehicle (which you have admitted you do not have complete control over) can be the difference between an "Excuse me, I'm sorry" and a trip to the infirmary or hospital.
