It's called Pleasure Beach, but last time I checked it was an amusement park, just like Cedar Point, Carowinds or any Six Flags parks. A park the quality of BPB is never in a million years going to be free to enter in this day and age.
BPB has developed far beyond the pay per ride days, and will never be going back thank goodness. The £6 entry has massively helped the park in terms of atmosphere alone.
But it's also just about killed secondary spend. People now buy a wristband and run around like lunatics trying to get 'value' out of them (that means as many rides as they can) they often don't sit down and take a meal on park, opting to dine elsewhere after the rides have closed, and the usage of arcades has declined rapidly to the extent that only 2 are left on park, plus one on the prom which can be accessed by none BPB guests. The National arcade, Log Flume exit, Beaver Creek, and South gate have all gone. Eateries have also taken a massive decline, with the Beach Restaurant, Magnolia, King Cotten and countless other smaller stalls being axed not to mention the state of decline on ocean boulevard. People simply aren't spending any money once they are inside, which is why I find is frustrating that the park has a massive advantage of an excellent location, which allows people to be potential customers until late into the evening, however the PPR system is so unreasonably priced only a mentalist would entertain using it.
However, with the £6 fee reduced to £5 and given back in the form of ride tickets or food/drink vouchers to people who don' buy wristbands and the ticket prices being reduced BPB could potentially be extracting money from new customers in the afternoon, evening and into the night on some days, money that we have all seen being spent on the pier as we are given the boot from BPB.
