once a word is integrated in german, using german grammar rules seems perfectly fine. but if i read "parties" im a german sentence, i would feel surprised however there are also plenty of counterexamples especially on the plural of foreign words, especially from latin, where a latin plural is expected. what this suggests to me is that singular and plural have to be integrated separately. "party" is essentially already a german word. "parties" isn't (yet) "party" distinguishes itself from "feier" because the later means "celebration", where as "party" in german can be used for parties that don't celebrate anything.
