Will she really get arrested? I don't think so - provided she doesn't get into trouble and bring unnecessary attention to herself - like a frolic on the beach like that dumb couple in Dubai and end up on the front page news of the Gulf Times. That would ensure she's arrested and deported.

If she's not driving but taking a cab, which is the responsible thing to do - that should be fine. But I would suggest that she doesn't go alone after being inebriated but rather have a pal with her to get her home safely .. maybe Flan boy over there would volunteer.
