These figures are not given out to the general public but if you ask, it will be something like heavy crowds, large, small, ect. If you are a regular park goer, you can gage how large the crowds are by past experiences, number of cars in the parking lot, weekday, or weekend crowds. This is the answer you will receive if you call and not the actual numbers.
I was just saying if you can find out what extension they are using for the alpha mailbox, then you can call yourself, they have a digital switchboard, you just call the #, it will say if you know your party's extension dial it now, it seems like it was something similar to 3497, and listen to the information yourself, or if your within radio range of the park, and know how to operate a scanner they broadcast it hourly on the ride operations, resale and public safety frequencies. I'll have to check, but there may even be a online scanner that streams KI radio traffic. If there is just check it around the top of the hour and you'll hear the official numbers.
