What is another way to say goodnight to a girl?

Answer:
Guten Nacht/Schlaft Gut- (These mean goodnight and sleep well in German respectively) or you can find out how to say it in whatever language you want that you think it would be romantic or cooler to say. Or tell her that you wish she sleeps well.
