I just wanted to let everyone know that we were over at IOA this morning and the coasters were closed due to the cool weather. They ended up starting late in the morning. We had an Express ticket and had got up early and got there in good time. We rode Spiderman and headed for the Fearfall ride, only to find it closed as it was too cold to run. We headed for the Hulk and it too was closed as was all the coasters. The temp needs to be at least 40 degrees. We were not aware of this and did not check the weather. So, I would suggest if it's going to be a chilly winter check the temps in the morning and decide 'whether' or not you want to get some more sleep or stand around in the cold. We were very pleased however when the staff members at both Fearfall and Hulk allowed us to enter the exit and go right on when we returned later in the afternoon explaining the situation to them.
