I understand why there’s a spike on the Saturday; would expect Sunday to be higher than a 2, but am surprised at the 6 on the Monday.
We’d planned a break from WDW on the weekend, but the Crowd Calendar suggests that this is the wrong strategy and we should go to one of the parks on the Sunday and not the Monday.
Generally the days at MK that do not have a MNSSHP scheduled have a higher crowd levels. Less people seem to go to MK on party days because of the decreased park hours. Closing at 6:00. That is what happened last year. Non party days were much more crowded. This was probably factored into the numbers which is why you are seeing a 6 on a Monday and only a 2 on a Sunday.
