One thing that I will add to this is that on our last trip, and I can't remember which ride line it was, I noticed that Disney has those chains in the queue lines that are magnetically connected. Not a minute later, a kid went to sit on the chain and the magnets were obviously pulled apart and the kid fell right to the ground. I am just waiting for WDW to get sued for that as a company with this much wealth is always a target.
What bugs me at times goes back to the idea of 'this is why we can never have nice things.' When the 7DMT opened, everyone was raving about the cool interactive features the imagineers built into the stand by line. This was so hyped that we decided to wait in the 45 minute line last summer. Now, the effects were neat. However, it is not neat when parents have their faces buried in their mobile devices while their kids are splashing themselves with water from the gem washing station in the standby line. The splashing got so nuts that other adults in line were getting hit with water.
Now I certainly look at my phone in long lines, but I always keep one eye on the kids. My wife does also, so between us that is a full set of eyes. And these so-called 'act ones' that the imagineers have added to some of the standby queues are cool. This type of activity is what ruins it for everyone though, so it wouldn't surprise me if this whole concept is negated or big cutbacks are put in place to tame down this type of interactive element. It is a shame but that is what I see happening. Life seemed simpler when phones and/or tablets were not there to distract you from the tangible real-world surroundings.
