Using this chart I made (on the left), populated from TouringPlans Crowd Calendar, I picked the last week of January for my trip based solely on these TP Crowd Calendar predictions, which showed very low numbers (indicated in blue in the Prediction chart), which has been typical for the last week of January in the past.
But while I was there I certainly didn’t feel like the crowds were low, as was evident by the number of people walking around and the high wait times for all attractions. (indicated in purple in the Actual chart).
In the third chart, you can see the difference in Actual vs. Prediction. Red being higher crowds than predicted and green being lower. There’s a lot of red.
I would love to hear from TP why they think it was so far off.
