If she's a professional, with all her proper papers and such, then I see no problem in it.
I mean, is there a law or rule stating you cannot bring take-out food into the Hotel?
I see people buy food and take it into hotels all the time.
Of course, its stuff like Burger King and McDonalds (Which I bet her food tastes ALOT better than, is better for you, and generally not polluted with all sorts of germs), yet, still, I don't see the problem here.
I mean, worst thing that can happen is she is a crazy Otaku who will poison our food, steal our plushies, and run like hell, right? ^__^;;
Yeah....thats highly unlikely.....or is it...?
