Pros:
You can play disc golf in Hawaii! Conveniently located near the Hilton in Wailua. If you're traveling to Kauai, you can get by with 2 discs, a midrange/putter, and a 9-11 speed driver. This is a bonus for traveling light. I don't think any holes are longer than 275 and only 1 hole, 6 is quite short. The teepads are a basic front of the box marker as seen in the photos, and there are next hole arrows hanging on trees to point you in the right direction. Also a map in the upper parking lot with the numbered teepad and basket locations. I really enjoyed playing through this course twice on my visit to Kauai.
Cons:
Course is fairly compact. You can get by with 2 discs, a midrange/putter, and a 9-11 speed driver. ( yes also a pro for travel weight reasons, but a more diverse layout requiring more discs would make it more challenging. )
Other Thoughts:
There are folks on the walking paths and/or walking their dogs and you may have to wait a bit for the traffic to clear. Hole 7 goes near the playground and there were some kids wandering near the fairway which may make you wait as well. Perhaps this is really a 3.0 course, the location tips it up to 3.5.
