I honestly think this is going way deeper than necessary.  The attraction CMs are not looking at guests' profiles to determine accommodations.  A single individual (like the PP) walks up and says "I need to leave the queue how should I handle that?" -- they can easily see she is 1 person, or they ask if uncertain about others standing nearby.
IF a return time were granted, it would have only been attached to the 1 individual, so again it doesn't matter how many friends & family are linked to her profile.  At that moment, for that attraction, she was 1 person asking for accommodation for 1 person.  No need for anybody to dig through an 
MDE profile.
