I'm sorry, but for those of you saying that the queue will be seldom used, you're only saying that to support your failing argument. This queue is going to be used every single day this summer, every single day this winter, and every single day from March until the end of April of next year... rinse and repeat. They're going to be dependent on this queue, as said before, to control the crowd volume in Diagon Alley... it's called land control. For those of you interested, Universal currently practices this with Forbidden Journey, running the attraction at half capacity in the mornings to move their guests into that massive queue line as a way to disperse crowds throughout the Wizarding World. To those of you who say that those switchbacks will be seldom used are those who aren't thinking of Universal as a world wide destination.
Am I asking them to spend 50 million dollars in sculpture to hide a show building? Absolutely not. What I am curious about is where Universal Creative is allocating its resources - because on one end you have details (as cited by members on this board) that most people wont notice, but on the other end you have amateur mistakes like the extended queue that just go without concern. As I recall - back in 2010 Mark Woodbury simply shrugged his shoulders over these same issues.
