honestly, it goes up and down... (bad pun)
when i was there a week ago, 10/10, it was running fairly well. went down a few times, but nothing major...
with the weather we had this last weekend, it wouldn't surprise me if it was down. it was very chilly and wet... and windy, which effects rides of extreme height...
your best bet would be to check their website before you leave for the park.
