I think more important than a crowd predictor is having a solid plan. We go on the 'worst' days and have a wonderful time. We are stuck though due to family schedules with work and kids school and sports our family vacations are pretty limited to 4th of July week or Christmas week. We will be at MK on the Saturday before the 4th of July. Will it be crowded? you betcha, will we ride everything we want yes! Use Josh, Kenny, Lines, whatever - just have a plan and it will be fabulous.
