I agree. Our last trip was DD7's first. She had no prior experience with buses that load
ECVs so she did have some questions about why they were in a different line and how the process works and was incredibly curious watching it all happen. She also made comments like, "Wow, she's driving that chair up the ramp like a pro," or "it's really cool that Disney makes buses that handicap people like that man can ride." With that last one, I did later have a chat with her that it's not polite to point out others' disabilities, but she really didn't mean anything negative by it and I certainly hope that if someone overheard they took no offense to it.
