High Maintenance Recruit

I am considering accepting a young photographer to our volunteer organisation. She recently shared, in an email, that she has a problem sharing a room with another co-worker (Our campus is a small facility, and singles are sometimes asked to share a room, at least until a single room becomes available). She admits it is a weakness she needs to work on, but that it is something very important to her. She says she is okay with sharing quarters during a short-term field assignment overseas.

To me, the fact that she volunteered this information tells me she may have a high maintenance personality which, in the future, may compel her to complain or be unwilling to take on jobs that may not "fit her standards of comfort".

Should I be concerned? Any recommendations?
