I just thought of another reason for Hermione to be in the tent, 
maybe so that we know what Harry is thinking.  In the book, we read 
his thoughts, but you can't do that in the movie.  Just an idea.  I 
really hope they don't cut the Yule Ball.

I wondered what in the book leads you to believe that Hermione 
thought the boys should have known about Krum.  It could be there, I 
just don't remember.  I remember having the impression that Hermione 
thought they shouldn't be surprised she had a date, but not that it 
was Krum in particular.
