Looks like 2024 is shaping up... Planning a weekend getaway to Paso Robles, a trip to Indianapolis for a wedding, a week- in Kauai, a week+ in Ireland, and likely a trip to Nashville for the board meeting.
I could write you a book on Kauai and I have tons of feedback since I'm going to insert myself here as my wife and I have been twice and it's my favorite place in the US.
HOTEL I'm a fan of the southside, but there's also a lot of people that would argue to stay on the north. Some of it depends on the time of year and whether or not it's rainy season. If you are anywhere south, Grand Hyatt is amazing. Worst case eat at the restaurant Tidepools on sight. It's amazing.
I'd take
Liko Cruises to see the Na Pali coast. So worth it.
Island Helicopters is also unreal are the only helicopter service that can land at the Jurassic Park falls and the rest of the 80 mins is breathtaking as well.
Waimea Canyon is a must.. 100% must. Not sure the budget or plan or what you like best but i highly suggest car rental.. First time out I made the mistake of renting a cadillac, which was a brain fart as a jeep or solid SUV is the way to go.
This is truly a place that's tough to fit everything in one trip.. Wailua falls, Hanalei beach, polihale park which is a massive crazy dirt road you have to drive down but leads to an almost empty beach and constant rainbows.
personally, I would in detail plan out days.. I'm typically a relax on a beach type of guy, but Kauai is the one place that planning out days leads to so many amazing experiences.
