What would you have Disney do differently during this period? Not build the garages? Not update Downtown Disney? You're not an architect, or an engineer or a program manager. You don't know what planning is going on behind the scenes and why things are scheduled and staged the way they are (in all honesty neither do I).
Am I happy with the sucky parking? No, I'm not. Am I happy with them taking away parking for valet? No, I'm not. But I work around it with my visits to Downtown Disney. I don't try to go on weekend nights, or if I do I'll find alternate ways without using the surface lots.
You, on the other hand, seem to take it personally. Just my opinion.
