You'll be cleaning the sand from the most unfortunate places for days to come.
Food will have that extra gritty texture and your clothes will need to be beaten stiffly with a broom.
But it'll be worth it. Sand tobogganing is just one of those things you must try.
And it's only a ferry ride away from Brisbane.
As someone who has done the dune buggy and sand sledding experience in Peru's desert oasis of Huacachina, the idea of hiking up Moreton Island's sand dunes on a hot day seems immense.
Where are the dune buggies to drop you off at the top and pick you up at the bottom?
I swear I will only do it once as I huff and puff my way up the slope.
But the thrill of zooming down the dune on a waxed piece of board -reaching speeds up to 40km per hour -is exhilarating.
So good, in fact, that I stomp up that dune a second time to try a different path to glide down the golden slope. My friend did a third.
Even better, though, is diving into the glistening turquoise ocean back at Tangalooma Island Resort to exfoliate using the sand stuck to your sunscreen-covered pores.
Day trips to Moreton Island can be as adventurous or as relaxing as you choose with packages offering desert safari tours, marine discovery cruises or whale watching.
The packages generally include lunch and full access to resort facilities for the day.
It's difficult to go past the one that includes wild dolphin feeding.
Get your elbows out to line up with the schoolkids and foreign tourists but just a few minutes hand feeding these majestic creatures is magical.
Just a 75-minute ferry ride from Brisbane's northside is the tropical paradise one conjures up when dreaming of a Pacific island.
The dolphin feeding day cruise, which includes sand tobogganing, costs $199 for adults and $149 for children. But a day out on the island, including lunch, is just $89 for adults and $49 for kids.
