My wife and I attended. We live up close to Cedar Point but love visiting Kings Island. I thought KI did a great job of hosting their first New Year's event. Lots of energy and activities going on around the park. The weather that day was miserable until around 7pm so that hurt the attendance. I thought by 10pm the crowds had built to a good level and International Street seemed busy but the rest of the park was pretty quiet. Assuming it returns for next season, we will be back for sure.
