Here's what I suggest: Make a copy of that plan. On the copy, move the attractions into the order in which you think they should appear. Then click 'Evaluate' to see what the software thinks your wait, walk, and free time should be.
One of the things the software does is penalize plans that cut it too close to things like meal, break, and show arrival times. So while it's possible to build your own plan that has you diving through the doors at Frozen just as the show starts, which would get you a zero-minute wait, the software's going to try really hard not to do that. We don't show those penalties on the plan, but they're there.
