Fun fact for you Disney fans out there In 1965, the "It's a Small World" ride began construction, officially opening one year later. Since that time, the average person's weight has increased by 25 lbs. Disney had to spend millions rebuilding all the boats to be bigger and more buoyant and had to deepen the river and add more water for displacement. They've also had to stock larger size uniforms for their employees for the same reasons. So if you ever wonder why the ticket price keeps increasing... well.
