the best way is like blackpool pleasure beach and pleasureland southport. they are pay per ride parks, tickets are around 50p per ticket and most rides are 2-4 tickets,(apart from the big one 9TICKETS) but they do also sell wristbands which are valid on all rides all day. it's great fo the perants who are just there for the kidds and buy them a band each and just a coupple of tickets for them selves and for us thrill junkies who just want just do as much as possible. The parks have always been very profitable and both just keep on building more and more rides, but i dont see how blackpool do it cause they have nowhere to build more rides and they cannot knock down old ones because mostly all of them are protected by a historic landmark certifiate.
