My son will be turning 3 during our trip in a couple of weeks. I know that 3 is the cutoff for free vs ticketed entry, and normally would not have a concern. But, my son is very big for his age...like off the charts for both height & weight. I was wondering if you all thought that I would be questioned at the gate (and if I needed to provided documentation for that reason). I am one of those people that would rather buy him a pass rather than keep getting questioned about it. Thoughts?
