I enjoyed my stay at Jacksons Retreat. They've got some great amenities, including glow worms on property and a private waterfall. Having easy, private access to the glow worms, close enough that I could reach out and touch them if I wanted, was very cool.
The Kiwi cabin was very nice. Parking was easy. Everything was clean. I slept well there. I ended up using my phone as a hot spot, so I can't comment on the quality of their paid wifi option.
The shared bath house mostly worked out fine, but the soap dispensers were empty and, for some reason, 2 of the 4 toilet stalls were inaccessible. (This is specific to the men's room.) I mentioned both issues at check-out and the woman at the desk indicated that she'd take care of them. Overall, though, great facilities. A notch above the other holiday park I've stayed at on my trip.
