We recently stayed at Wahoo Ranch. We booked and prepaid for a powered site with water. When we arrived at 2pm we were told our booked site had been given to other travellers and they forgot we were coming. There were only two powered sites available both had campers on them.
The hosts were friendly and offered us an alternative. We were offered two sites close to the Bruce Highway. One was an opened grass site, and the other was a gravel site with a small amount of scrub behind it. We chose the gravel site. The hosts ran a long extension lead from the shed so we had power, and potable water was offered, but we used the water in our own caravan tanks.
The biggest downside was the constant traffic noise from the Bruce Highway. Trucks and cars passed throughout the night, and we had a very poor night's sleep.
While we appreciated the hosts' friendliness and their efforts to provide an alternative, we were disappointed that our booked site wasn't available. We thought really what was the point of booking it through HipCamp.
For us, this wouldn't be a place we'd return to. It may be suitable as a one-night stopover for travellers passing through, but we wouldn't recommend it for anyone looking for a quiet, restful stay.
