That's gonna be a hard question for most of us to answer. The majority of us live on Oahu, but maybe some go to Kauai often and they can chime in? Idk but I have only been to Kauai a couple of times and it has been over a couple of years since I last went. But if worst comes to worst you can probably just ask the locals there and they can tell you whats good and whats not.
Sorry I couldn't be of much help
