The past few four or five times I went to the park, I didn't have to wait more than an hour. If you are infront of the vending machines, you should be at an hour or less. Even with Dragster closed, and the parking lot loaded, the waiting time for all the rides seem to be quicker this year. Even when they have Millenium posted for an hour, I didn't have to wait that long.

Life has it's ups and downs, might as well make it on a coaster!
