I was always under the impression that snakes are not that aggressive, unless you really anger them. But waking up with one in your face is way different, you startling can startle it. I still think a hammock is a great choice. Like Lori said, look in to War bonnet, Hennessy, clark...They have fully enclosed bug nets and different entries. I have a Hennessy with a bottom entry that Velcros up. No snake will be able to get to you unless he was a sickly deranged zombie snake.
