Hmmmm... Being a mench and a worrier, I understand with the "pack her up" theory, and agree the if there is a doubt, there is no doubt- get out.

But, she's you kid Ben, and she is 19- I can't believe she going to ignore a situation when getting out is a good idea. You've spoken with her about plan B, staying and if need be holing up on her own, why you don't like. What was her plan C? Perhaps she stays until Sunday, then takes a red eye out? That gets her out of the way, and with her qualification dive. Or maybe there is a land route that can be use if it must?
