Yes that was us with the pink headphones.
The stroller is actually a bike trailer - it trails behind a bike going at what ever speed a bike can go when it's got something like that attached to it. Certainly faster then most people can walk or run. It's first and foremost this. Why is this important you might ask - it's important because it was built to take a spill that a bike going at higher speeds (faster then a runner) would have. It's build to keep the kid as safe as possible in that type of situation. It has a roll bar, it's bars are bigger and stronger then a typical stroller think the type of bars used for a mountain bike - it's made extremely sturdy. There is a harness and a seatbelt - it's made to keep a child safe if the bike took a tumble. Of course as a bike trailer you would put a bike helmet on the kid as well. No it doesn't have air bags but it's much safer and certainly much stronger than a typical stroller.
They hooked the stroller in with 3 hooks - 2 at the back around a large bar and 1 at the front. They wrapped the seatbelt around it. She was strapped inside the stroller as well. Honestly if there was a bus accident - she would probably fair better then most of the rest of us in that bus since we are not strapped in.
There was no risk of the hooks breaking, bending or otherwise damaging the stroller again think the strength of a mountain bike's frame.
There is no extra writing on the tag - it just has the symbols, the words Disney world and a line for an expiry date.
I get that the tag was only meant for the parks - heck that was why I started this thread in the first place. But what is "official" and what is practiced isn't always the same. (doesn't make it right it's just the truth) So what I experienced was that the drivers respected the tag. I needed that to get on the bus first (or almost first - was once or twice that wasn't the case but since now she was in the stroller the whole time- it didn't really matter since she had all the space she needed.) The fact that they decided strapping it was the best option worked well for us. We were on the bus a total of 15 times. Only one driver had never seen the tag (actually held it and looked it over) the other wasn't sure what we had but once we explained he was fine with it. Not once in all 15 trips did anyone say they were just being nice to us. Not once did any hint or suggest an alternative because what they were doing could be dangerous to us our kid or to others.
I'd like to think 15 adults, and the parents of the kid in the stroller would only want the best and safest possible way to transport the kid in question from one place to another. I'm a responsible adult. The State of Florida gave these folks a licence to drive buses probably with some training how to deal with transport mechanism for wheelchairs etc., Disney saw enough in them to go through a whole hiring process to have them as their bus drivers and again probably gave them training on how to use the specific transportation mechanisms used in their own fleet. I love my kid just as much as any of you love yours. The kid was not in any danger, the other folks in the bus were not in any danger, the stroller was not at any risk of breaking. Had I felt this or if my hubby felt this was not a safe thing to do - we would have been the first to holler.
All I wanted to do was assure others going to Disney not to worry about stuff that doesn't need to be worried about. Look - 5 pages of strategizing how to get kiddo from point A to point B and in the end - it wasn't a worry at all.
