You could try taking her phone, laptop, computer,all of her money, etc. Tell her you will give them back to her when you get where you are going in Hawaii. Of course that does not mean the family members she will be staying with will not take them from her.
This behavior is common with teenagers. I know how physically, mentally and emotionally exhausting it can be for the parents. Have you put her in counseling ? Are you in counseling ? It can help parents to get professional support and advice.
Don't be surprised if she wants to cone back back home when the new wears off. This is also common. Be sure and find out what the schools in the area require for her to be enrolled. Be sure you give the family members she will be staying with. The legal documents they need to give permission for medical care and other things.
