I couldn't find the answer to this during my search, so hopefully someone can help.

My wife has to switch from terminal 1 to terminal 2 to catch the next leg of her trip. The particular flight she is on has been landing in the low B's (i.e. B7). From this point, how would she get to terminal 2 for her flight that has been leaving from the low F's.

She is not a travelor, so she is terrified of the possibility of getting lost in ORD.
