Thank you guys, that was a great experience!
If you get the opportunity to do it, just do it! It is so much fun! You'll get a nice shuttle ride out to Arthurs Point and back, if you don't have an own transport.
The staff at the reception is very friendly and helpful and I felt really comfortable.
The skippers are experts, well trained and passionate about driving the jets.They'll do heaps of spins which I really enjoyed a lot. The scenery is just amazing if you got time to look around.
Especially in winter bring gloves, hat and glasses/ski goggles for protection against the cold, as you'll freeze.
They take a few photos before, while and after the ride. A negative point (to me) is the quality of the photos (didn't convince me at all), especially for the price.
All in all great fun, all year around, for the whole family or with friends! :)
