Then why does she ride on the monorail? It doesn't have to storm for the power to go out. The fact that this happened due to a storm is a coincidence, but storms aren't the only reason.
There's other modes of transport to get to and fro at WDW. I'm sure that there were more than a few claustrophobic people as well as others who don't like being suspended at heights on board. It's just a chance you take when you get in. To mitigate the chances, you find an alternate way to travel.
Hopefully she never has to experience being stuck, but it's always going to be looming out there, that it just might happen.
We do not ever take the monorail any longer, at first it didn't bother her but after sitting for 20 min's one time out on the rail not sure why didn't really matter though she will start to panic if we even ask her to get on the monorail.
Not all families are like mine I have friends who I know for a fact if my daughter was theirs would force her on the monorail any how. Or someones fear could of just started at that moment realizing what had happened and they were stuck, guess I'm just saying Yay the tweet reads as an over reaction but people shouldn't just go to making jokes about it because that person could really have been having an issue (or just wanted free stuff from Disney).
For a while she wouldn't take the ferry either so we just didn't go to MK. Now she doesn't mind the ferry.
