I've stayed here once. It was 'fine' and kids certainly get a lot of value out of it. It's self rated three stars and I'd say thats about right.
The advertised package has about 15 months validity, so this price will be the cheapest package available in that time. It's likely most folks will be booking this during school holidays, given the resort is heavily targeted at kids, so i've done a comparison for the first week of July (next week). YMMV.
A few points to make about the package inclusions:
Free kids club session - not a perk of this package, and 1 is free with every booking made directly with the resort.
I've priced this up for a family of 4 with two teenage kids - this just kept the math simple where some pricing varied for younger kids, so this will show the most value. Younger kids will cost less in some places so the savings are also less.
Most prices i've sourced directly - Dreamworld, Jetboat, and the resort. Some i've had to take a stab. You might disagree with my pricing and you're welcome to, I couldn't care less, so have at it.
'Thrill n Chill'
This is a minimum 5 night package, so i've quoted it for July 1-6. This does avoid the weekend peak room rates, so the per night price for 'room only' was about $300 per night.
The package includes:
5 Nights accommodation ($1503.75)
2 day dreamworld pass ($129pp)
Breakfast each day (22.50pp)
1 x Kids Club (included)
Ice Skating Session ($20pp)
Kids get free Paddle Pop ($3pp)
Purchased Separately: $2555.75
Advertised starting price: $1299.00
Actual Package cost for these dates: $1679.00
Saving: $876.75
The continental breakfast does a lot of heavy lifting here - at $22.50 per person, with 13 year olds charged as adults, this adds up to $450 for a 5 night stay. When it's included, Families should try to get their money's worth out of it, but as an optional extra paid separately, I can see most families opting out of this cost and opting to self-cater, or pick up a cheaper breakfast option where needed.
"I Want It All"
This is a minimum 7 night package, so this one is quoted for July 1-8. Weekend peak rates are unavoidable so the room only price for this period increases to $326.04
The package includes:
7 Nights accommodation ($2282.28)
2 day dreamworld pass ($129pp)
JetBoat experience ($59pp)
Breakfast each day (22.50pp)
1 x Kids Club (included)
Resort Activity Credit ($150)
Resort Food & Beverage Credit ($250)
Dinner for 2 in Penguins ($164 max)
(using two of the most expensive entrees, mains and desserts not including platters)
2 Welcome Drinks ($20)
Late Checkout (Price unknown, only an extra hour)
Purchased Separately: $4248.28
Advertised starting price: $2599.00
Actual Package cost for these dates: $3378.97
Saving: $869.31
Again, breakfast is going to run you $630, which is going to take up the majority of your savings here if you opted for something else. The resort has plenty of things for you to spend your credit on, but as is usually the case with included credits, you'll either not spend the entire value, or you'll have to top up your final credit spend with some extra when it doesn't quite cover the full balance. You'll have to do your research to use the credits to their best value, but you can definitely make it work.
There's only $240 left in the savings after breakfast is taken into account, so a thin margin if you aren't going to use everything that's included. The dinner pricing is the maximum possible, but could easily be as low as $70 cheaper if you ordered the three cheapest items on the menu.
Dreamworld Annual Passes only run you an extra $40. If you're a savvy holiday planner, you could book week 2 of the holidays this year, and week 1 next year, and save yourself almost $360 on park tickets too.
TL:DR - there is value in these offerings, provided you'll use all of the inclusions.
The Thrill N Chill gives you the most value if you aren't likely to make the most of the inclusions as even without breakfast, you're essentially getting 2 days at Dreamworld for free (though if you book this across a weekend, the price is likely to increase a bit).
The I Want It All package is less valuable unless you spend a lot of time at the resort using their facilities. After paying for your room and dreamworld passes, you'd still have about $500 in your pocket to spend on whatever you wanted rather than trying to spend it at the resort, though the jetboat experience (if you like that sort of thing) would take up almost half of what is left.
