At the meeting, Fleur offers to help set up safe houses overseas and even offers her family's vacant apartment in France to the Order. She assures them that her parents wouldn't ask any questions nor really question it if she requested the place for use by Bill and herself. They would have free use of the place until May or June if they decide to use it.
Also, Fleur offers (along with Bill too if Lyn wants) to reach out to the goblins as her job has her in contact with them and they are familiar with her somewhat.
