Last year, even with a tarpaulin to shield the car from the wind, it was still quite cold. This year, the car has pull-down windows, so even with a windy -3 degree Celsius feel, it's not too cold. The kids say they want to come again next time! We bought our KKDay tickets on the way, and just confirmed the barcode at the counter to enter – no waiting, very convenient!
