I was checking crowd calendar on another website. The time I really want to go to Disney the crowd level is a 8 on all days. If I go a week later the crowd level will be a 8 on 4 days and a 7 on two days and a 6 the day before we leave. Does it really make a big difference with crowd levels at 6, 7, or 8? Please help me out with my decision and thank you.
