I guess you guys are right about finding enough wood, it shouldn't be a problem. But I have had the experience of camping on a small island site and having to paddle to shore to find wood. I guess that's easy enough to do but it sure cuts into your fishing time.
Another politically incorrect way of assuring yourself of dry wood is to cut down dead trees, especially pine. We usually check the tops first for any signs of green, if there's none, we snap a few branches; if they snap crisply it's a taker.
But enough on that topic, have a great trip!
