I've got two kids, 5 and 8.
They want to goto the Gold Coast in January 2012.
I figure we'll go for a week and ideally I'd like to use one of those unlimited entry passes because they tend to tire after about 3pm (9am start) so we'll probably go back to the hotel then each day.
It looks like Sea World/White Water World/Movie World are on one pass, and Dreamworld + others are on another
Which is best for kids this age??
Movie World & Sea World are both must-see IMHO; I've never been to WWW coz the weather has just happened to turn nasty at the times we've been ready to go, so I'll have to defer to the pro's on that one! Sea World often has good play/stay packages for families too IIRC, that might be worth investigating as well.
Oh, here's a MW tip…don't spend all your time just waiting on the big name rides & miss some of the other stuff at Movie World; the Loony Tunes River Ride is bloody great for all kids aged 3-93, and there's rarely a line at all! :)
