I don't think you have to worry there, it's not like they are going to be watching your every move. Additionally, the point of the DAS is to prevent issues in the queues, so why would Disney say you are abusing the system, if it is doing its job?Right with you. Similar issue here for why I have used DAs. I'm often there alone so having to run to a rest room is a huge problem when the line is long. How will they decide if I'm abusing the system?
I think this is more about those idiots that get a DAS and show how to abuse it on YouTube, tictoc, etc.
