I was there all day on Friday and till about 5 on Saturday. I do know The Vortex broke and after that they only had 1 train The Racers had 1 Blue and 1 Red going The Beast had only 1 train going and the line was an hr+ wait and Diamondback was an hr wait as well and they had 2 trains going Saturday during the rain. I did not mind the rain all that bad as it wasn't heavy but i did mind waiting in line for an hr in the rain if there had been normal wait times i would have stayed.
Also on a side note it doesn't make sense to say certain rides are open till Midnight and then close them at 8pm till fireworks are over which is after 10pm. Its kinda misleading depending on how you look at it.
