I attended Christmas at Kentucky Kingdom tonight. I really enjoyed the sledding hill, and especially enjoyed that their Larson Drop Tower was open! As has been pointed it, there definitely is room to grow the event's footprint in the combing years, but the buildings that were covered in lights looked very nice.
However, I was very disappointed that Kentucky Flyer was closed our entire visit. I asked and was told that the minimum operating temperature is 32 degrees (it was 31 degrees when I asked). I assumed that it would be a lot lower than 32 degrees considering I have ridden Mystic Timbers in considerably lower temperatures. I understand it's a different manufacturer but...really? Roller coasters in Europe operate in the snow all the time; I find it very hard to believe that a wooden coaster would be unable to function just one degree colder than 32 degrees.
I noticed that a ticket price at the gate was about $40. This seems unbelievably high to me. I got in for free with the Kings Island employee reciprocal agreement, but I could not imagine paying $40 to ride the sledding hill, ride some flat rides, see lights, and find out that the only coaster they run was closed with absolutely no warning outside the park.
