You do realize the Batman and Dick are master escape artists? Did Gambit and X-23 travel the world and train extensively in how to track someone, let alone two of the greatest hide-and-go-seek players of all time?
Gambit did travel the world but he did not do it for the training. He was raised in the best thieves guild in the world. X-23 had the best money could buy brought to her.
It is a moot point anyway considering there is going to be no traps set.
