I live just about 5mins up the freeway from Dreamworld.. and i can say from when i was a child, i absolutely loved it! Actually i still do...

There are animals and stuff to feed there, kids shows on - if they take there togs they can go for a swim, train rides and a whole heap of fun stuff.. and the rides are brilliant - although i think there are some big kid rides there now that might not be suitable. Just a word of caution though.. It is always packed on school holidays, so lines are unreal... But obviously you know, rides are unlimited so the kids can jump on as many rides as they please!
