There's this quote, that in my opinion applies here: "There is no book more boring than a book of jokes." I think that if you pressure yourself to write a funny story-hour it might end up being counterproductive. In other words, perhaps you shouldn't try to force the humour out of it. Some of the funniest moments (in games, movies, books, what have you) happen in situations of great stress / drama / fear. Let the story progress naturally.
Personally, I don't really like stories that are told from 7 different perspectives, it makes me feel like there are too many lines of thought, and makes it harder to get a good overview of the story. But this is really just my cup of tea, not a scientific opinion
