We had a lovely trip! We actually didn’t meet Kai, but his dad helped us out a couple of times and they were both really responsive.
I would suggest putting something in the binder about the possibility of parking out near the street (we did this because the parking area within the gated yard was so tight.)
It also took me a few days to remember to buy entrance to the City of Refuge early in the trip ($15) to have parking for the week to go snorkeling at Two Step.
Thanks so much for your help and your lovely rental!
