Even on saturdays right now if you can take the heat Intimidator has around a 20 minute wait mid day. And when I say take the heat, the heat index was almost 120 this last saturday. The mister fans are nice but they don't help too much if your not used to the heat.
My game plan for a saturday right now would be this; Make sure your at the gate at 10am, go ride everything besides intimidator, then enjoy the reason you are here. Intimidator does get a 1hr wait the first few hours as thats what everybody wants to ride, I don't know for sure as I can't really see any other rides queue, but I have to imagine the other rides are walk on when our queue is that full at opening.
Roller skates maybe(depending on color), naked, no. Steve does let people fly naked now thou, ask him.
