Recently stayed at The Outrigger and had a pretty good experience. We probably would have enjoyed a lot more if it was in spring, but nevertheless, it was still fun. Spring would have gotten us out to the balcony in the evenings for some BBQ and star gazing, something we can't do with a baby in winter with the winds blowing hard.
The driveway is good if you have a sedan, but tricky if you drive an MPV or full SUV. We drove a Hyundai IMAX and ended up parking in front, walking up the slope as we didn't want to damage the trees or the car.
It was relatively easy to self-check in if you follow the instructions. One of the heaters was faulty, so we texted Simon. He got it changed for us the 2nd morning promptly.
Full kitchen, so we could whip up some quick breakfasts and late night suppers. Very helpful if you need to have some food before taking meds or if u need to cook for children.
Do bring your own toiletries. There were clean fluffy towels which were really nice. A slight downside was the beds were a tad too soft for our liking. Otherwise, it was a good stay in Gnarabup.
