I agree with the majority of what you said, and I am hopeful DLP will receive more capital in the coming years. As for needing double the equipment, not quite...
While you would need more craftsmen and artisans working on the projects simultaneously, you could develop both lands with the same equipment. For example, Frozen land is at the phase of vertical construction, all the equipment like excavators, bulldozers and dump trucks that were used to prep and grade the land aren't all being used now; Disney could have been using those same machines that prepped the land for Frozen, and start on the Lion King plot of land. Rather than wait until Frozen opens, and the equipment is moved offsite... only to bring them all back months or a year or two later, just doesn't make sense.
