I agree. I liked DCA 1.0 because even though the execution was poor I saw that it had a good foundation on which to build upon. There's no question that the park at opening was built on a shoestring budget and it backfired big time. Since the mid-2000s there's appears to be a greater investment from Disney in P&R projects resulting in a marked improvement in the consistency and quality of work from WDI.
But let's separate design from construction, and be careful to lay blame in whichever element had the failure.
Certainly contractors get beyond their experience and get into trouble.
But most of what is complained about around here is the result of Disney controlled design/project management.
