We experienced the same old "lull" with shorter wait times when parades were on and fireworks were going. I am supposing that a great many people faced with making fastpass options so far in advance and not armed with as much info as many people here are, simply schedule things not knowing or really caring about the times. They then skip a fast pass for a parade or fireworks show. Plans that far in advance don't always go as planned. kids get cranky etc.....so , at least for now it appears that this time period is a good one to hit rides otherwise jammed by crowds. That is what we experienced anyway. We just went in April and again in May.
