I'm a planner-to the nth degree. I don't like surprises and I agree with accsys. I also don't mind planning my activities around where we are going to be. That said, you can always book in advance based on how liberal the campground cancellation policy is and then change if your plans change. My experience in the Maritimes is that peak season ends about mid-August, with the exception of Labor Day weekend. If you aren't picky and since you have a smaller unit, then go for it. It's whatever works for you-if having to be somewhere at a prescribed time stresses you out more than having to hunt for a place to stay, then don't book anything and just ride the wind wherever it takes you.
