We had a great time with Jonathan's wild kitty. We believe it is indeed one of the best ways to enjoy Kauai. The tent was comfortable and very easy to set up and close, we went from 30/40min on the first day to no more than 5min on our last.
Jonathan and Michael are very nice people. However, our impression was that they could spend some more time on helping out the customers during check-in. The instructions for setting the tent are sent via video, while a practical demonstration could definitely help inexperienced campers such as ourselves and ease our stress. Some of the tools that were provided were a bit defective, nothing major for us (the umbrella, a snorkel, and the french press) but some additional care could be used there.
As for the pick-up and drop-off from the airport, if you feel a bit adventurous there is a bus station not far from the check-in place (2$ per bus ride). Uber and taxi were not reliable options at the time of our visit, very few drivers on the road.
