My family is going to WDW in the end of August, and my wife and I are considering applying for the TSA Pre-Check. We will be traveling with my two sons aged 5 and almost 1. My youngest son will require formula and a stroller to be brought through security. Understanding that the pre check line is supposed to speed up the security process. How does TSA feel when you stroll up with formula and a stroller that will require "special" attention? Will they make you go through the regular security line? Is it even worth it for my wife and I to get the Pre-Check?
