Frankly, as long as you're staying for a few days, maybe she will have time to come to her senses and realize she needs to go home. Right now she is probably still a little shaken up, especially if she can't remember anything. If she's scared, she's going to be looking for any normalcy, which is what staying put would seem to give her. Let her think about it for another day or two, IMO. She just may surprise you and come back around, esp. when she realizes that staying in FL would mean being near the people who did this to her.
*praying for all three of you*
