Again, building to hurricane code complicates what would appear to be a very simple design. Open-sided "shed" type buildings are the most vulnerable structures in hurricanes, because the wind gets underneath the roof and pushes it straight up. Because these sheds are the only cover on very complicated mechanical systems that are delicately balanced, they have to be built extraordinarily strong to compensate and to protect the ropeway mechanics from wind damage and flying debris.
So, is Disney picky and relatively slow? Yeah, I'll agree that they are, but I think that in this case that wasn't the primary reason for the lackadaisical-seeming project timing.
