Amusement Park admission structure where you pay-one-price for all rides, shows and attractions and is often called a POP ticket. The other option if available is to pay-as-you-go, in which case you'd use tickets for the rides, attractions and shows. Disney Theme Parks are examples of POP admission parks, and Knoebels Amusement Park is an example of a park that has POP as an option on selected days, but always offers the option to pay-as-you-go.
