That's a very good deal. (When booked online, £35 at the gate )
There is a better offer though - if you are going on holiday to the park and plan to visit two days then the "Big Value Pass" is a great price.
Priced at £50, it gives you two wristbands to be used on seperate days as well as a Pleasure beach pass (allows you to enter the park without going on any rides), Ripley's believe it or not admission, two rounds of Pleasure beach adventure golf, an Ice skating session at the Arena and admission to Pasaje Del Terror.
You can find out more about the pass here: https://www.blackpoolpleasurebeach.com/book-online/wristbands
It's a great offer considering that, aside from money off wristbands you save £32.48 off the adult admission fees of the other things included in the Big Value Pass - not to mention the fact that you save £10 on wristbands.
