Ha, I can totally relate. We stopped planning out our days a long time ago, (and not just with vacations to Negril) because sand gravity just took over each time. Now, we just go with the flow, if we feel up to doing something, we do, if not, we are cool with it. I think once we had kids and started traveling with them, we also just became a lot more flexible with plans. I think you will have a wonderful time with or without plans.
