Warning about the TP making me arrive late

How do I know which show or meal or break this warning message typically is referring to? I see that message quite often when I hit optimize button.

“The plan may have you arriving at a show, meal or break a little later than you’d prefer, but probably close enough. This shouldn’t be a major concern, but just something to be aware of. If you’d like to arrive earlier, your options include selecting fewer attractions, taking shorter meals or breaks, or extending your day in the park.”

You need to check the arrival times of your shows, meals and breaks - there’s no other way to know which it is.
