While this definitely does not compare this experience, it did show this young person the utility; in the early 70s when Disney World opened, we used the trams in Fort Wilderness to get around for a week; shopping and back and forth to the camp store, going to the activities in the day, evening and at night. Just running around. Did this all with and without parents, and I think they were possibly electric at that time as they stopped right outside your campsite at the corner and must have been very quiet, or maybe diesel, just don't recall. We simply learned the schedule, hopped on and then off, and simply had a great time. Like many things Disney, I thought I was looking at the future and was pleased.
