Also, after my kids rode Pteranodon Flyers over and over, one of the TMs gave them both a button that said, "I'm Celebrating! Frequent Flyer on Pteranodon Flyers." That was a nice touch.
We've been to both Universal and Disney many times, and by far the coolest interaction we ever had with any employee was at the Pteranodon Flyers.
It was our spring break trip last year, which coincided with my DD's 7th birthday. She was wearing her birthday button and a Flyer ride TM started chatting with her, noting her name reminded him of a favourite TV show. We joked back and forth, and when we got back to the station he high-fived her and said we had made his day.
As we were turning to go he stopped us and asked us what ride we were going to hit next. We were planning to head to Seuss Landing, but I had a feeling where this was going, so I interrupted my daughter and blurted out "Forbidden Journey". Sure enough, he got on his phone, gave our name to the TM at FJ's entrance, and we were escorted to the front of the line.
Definitely the highlight of that trip, and a great memory.
