Wow. What a place is this. I have just entered and spoke these words. You can find everything inside. You will find many thrilling rides and so much things to see. You need to pay once and you can enjoy everything you want. Personally i like water park so i spent my more time there.
Forget Disney! If you're actually looking for crazy, blood-blanching rollercoasters happy valley is the obvious choice. Rides are insane and really get your adrenaline going. it's a bit far out but makes for an awesome day trip. nice balance between the adult rides and more relaxed attractions. Food wasn't amazing but that's not the reason to go to a theme park haha. really enjoyed the day spent there - caught about 12 rides and stayed inside until 6pm.
