I can't remember exactly the order, but in the Maritimes, the March Break weeks are all different. I think (someone correct me if I'm wrong please) that it's NS the first week, NB the second and PEI the third. I've gone twice on our break, but they were my only two trips I've taken, so I've nothing to compare them with! I found that I got a lot more done when I followed a touring plan, so I didn't really have a problem with the crowds.
