First of all, if her chair was broken by another Guest, I hope you all reached out to Guest Relations - or at the very least, the nearest CM - to let them know what happened.
I'm sorry that your daughter had such a rough time on your last visit. But over the last 10 years, I have personally seen a reduction in the kind of incidents that used to plague this community on a regular basis; overall it seems as though everyone is much more understanding and accepting that Guests of ALL kinds are welcome at WDW.
Don't worry about what anyone else thinks of you at WDW - your chances of running into anyone you see on your vacation at WDW again? You have a better chance to hit the Lotto jackpot AND get struck by lightning on the same day.
And if you do? So what. You have a legitimate need for a mobility device - and I personally think you are very smart to use every tool at your disposal to have the best possible trip. Anyone who judges you does so from a place of ignorance and fear. Ignore them. Seriously.
At the bus stops, don't get caught in the whole "everyone is looking at me" trap. They are looking
AT THE BUS because the damn bus beeps, flips out a big 'ol ramp and carries on like it's the end of the world. YOU just happen to be there, in their line of sight. And let's face it - for the majority of people who never have had to deal with mobility issues, it can be interesting to watch, simply from a "Oh, that's how they get on the bus" perspective.
If - and this is a big IF, because no one probably will - anyone says anything like "must be nice to get on the bus FIRST", then you simply give them a big smile, and say in your sweetest voice "
Yes, but remember that we are always the last ones OFF of the bus when we get there!" and then turn away - don't engage further. Trust me, it shuts them up.
And... if you run into that ONE PERSON who just won't let it go - who is just determined to ruin your day and everyone else's? What if you just can't ignore that person for some reason? Then you give them the full Mamabunny treatment: You give them the biggest, most dazzling smile you have, look 'em straight in the eye, and in your best southern drawl, you say this: "
Bless your heart!"* And then you wave like the Princess you are, and sail off into the sunset, with the sure and certain knowledge that Karma has a long, long memory my dear.
Have a lovely, wonderful trip. And don't worry - they are all too busy posting lunch to Instagram, and taking selfies to notice much anyway!
*those of us from down south know *exactly* what that means...
