Efteling Theme Park

[Ash19]

I'm just wondering does anyone know what a red dot in calendar means. I had planned to go in the summer but I'm getting a price of about 700 cheaper to go a Friday to Monday end of November flying into Eindhoven rather than Amsterdam for winter efteling however on the Sunday there is a red circle beside the date. Does anyone know what that means. The winter efteling looks amazing but would there be massive wait times at weekends.

Think it’s high season (I’ll just check)

When looking it up it just says special conditions. Can't seem to find much about what these are. I don't mind waiting 20 or 30 minutes for rides but longer then this would make it hard with 8 year old.

When you click on the day it comes up with the following message

(Corporate) event
A (corporate) event is taking place and we expect it to be busier than usual in the park on this date
