I remember we used to take trips in September and January. The resorts would be beautiful and quaint. And the parks were managable. Now in September and January it is endless people. Between the tour groups, cheerleaders, and the traditional guest it is no longer a slow season.1. Parents take there kids out of school for a vacation which use to be the quiet times fir the resorts. I have. No pity when I hear the parents crying around about how packed the parks are.
