We were there during the last part of Jersey week this past November, Nov. 10-14. It was crowded but not unmanageable. The problem was the constant MMVCP that made MK very crowded on the non-party days. We also went this past March during spring break, and that was much worse! Before that, we were exclusively summer vacation trips, which were also very crowded. Honestly, no time is a great time to go other than September now, but then you risk hurricanes. But I would go again during Jersey week over either spring break or summer vacation, if that helps ease your mind!
