In my canon playthrough, I hid the bite and I went on my own. Figured it was the most courageous thing to do, rather than burden the group and potentially endanger them if I were to turn. Besides, more people to guard the boat can't be a bad thing.
In my non-canon playthrough though (whereby I make decisions I might have made differently in hindsight) I showed the bite and brought everyone except Ben, who I left to guard the boat. Praying he doesn't fuck it up.
