One of my biggest Disney challenges in the past 2-3 years is the inconsistent Cast Member quality and obvious lack of training. If this issue happens when you need towels or a refill of a beverage, it certainly isn't "Disney level service", but it's a minor inconvenience.
When these issues happen with
DAS, and the Cast Member failure can cause a horrific experience, great anxiety, or even life threatening medical emergency, it's simply inexcusable. We had such an experience, and it was handled poorly, to say the least. I feel as if the perception by Disney is that DAS provides convenience, and that is simply untrue. For many/most, it is the difference between being able to experience something safely, or having something pretty awful happen. It certainly isn't a place to cut corners or throw untrained, immature CM's into.
