It's clearly better to have somebody spending no money than some money?
Economics is not Amanda's strongest point...
I agree that in the most cases, people would have bought the wristbands anyway (at whatever it is for a single ride on the Big One now, I'd be shocked if people were stupid enough not to). I don't have a problem with that at all, I think people wanting to go for more than an hour and on a few rides would have always got the wristband and the entrance fee won't put them off.
However, it's still the same scenario. Person goes in, goes on maybe the ghost train, Big Dipper, plays a couple of side shows and buys a hot dog. Multiply that by maybe a 1,000,000? They've paid more per go on the Ghost Train and Big Dipper than a band holder has. So right away there is more profit per head from "casual" visitors than band buyers. Band buyers are also more likely to leave the Pleasure Beach to find food and return later as they have a more prolonged stay.
I think the decision is purely a social one, and has nothing to do with actual economics. I think Amanda sees the people who don't want to buy bands as being the "types" she doesn't want in her park. Fair enough, but you have a sea side funfair in Blackpool love, it's not Vegas...
Anyway, it'll be interesting to see if the new dodgems are pay per play or not. I'm also very interested in what the plans are for the huge space
