Here is a heads up on a deal running at the moment:
$30 for 30 days: Unlimited entry to Dreamworld, White Water World and SkyPoint from 1-30 March, 2014. However, if you want to purchase this deal, you must purchase it by THIS FRIDAY, 28TH FEBRUARY, 2014. See here: shop.dreamworld.com.au/Tickets/30day-UWP
Unfortunately, it does suck for those who have been organised and pre-purchased tickets for their trip in March, but, if you haven't, then, it might be something worth looking into. :)
P.S. Don't forget that there is another deal running at the moment (for those whose trip will be BEFORE 4 April, 2014): dreamworld.com.au/Visitor-Information/SAD.as… which entitles you to 50% off a ONE-DAY World Pass (maximum of 4 one-day passes can be purchased per Shop a Docket offer). It is a good idea to print off the Shop a Docket from the website (you can use 'Surfers Paradise' as the location to bring up the docket): http://www.shopadocket.com.au
P.P.S. Make sure to 'Like' Facebook for updates on Dreamworld deals and also just keep a general eye open online for any deals that pop up. I think this is the first time in a while where I've seen Dreamworld offering deals such as these during periods that don't include Winter.
