I think there's a lot of people out there that remember the days they could just walk in the Pleasure Beach instead of this day and age that requires everybody to buy a wristband to get any rides in due to the ludicrous PPR costs. So this stops some people going to the Pleasure Beach. If at the very least they charged £1 per person to enter to cover security costs and then lowered the PPR costs they would attract more people to the park. Some people don't want to be forced to choose one option (wristband), but if you can get them in, let the rides sell themselves then people would impulse buy either one off rides (that may account to more than a wristband cost) or would buy a wristband. The current model just keeps too many people away from South beach nowadays and ultimately affects surrounding businesses.
