Good Marriott hotel right on the bay. Though not directly on ocean I wound up liking it better as you can easily see ocean and surrounding mountains that create the bay which gives you more to look at while laying at the beach or at the pool. Additionally swimming and playing in the bay is much safer.
Rooms were nice, I'm a hotel snob so would classify as good not great. Almost every room has an ocean or bay view. I requested a pool view and have a view of both the pool and ocean without paying for the ocean view price. Be sure to request a high floor. That ensures a better bay or ocean view room and helps with the wildlife noise. There are a lot of wild chickens and roosters all over Kauai. Not a big deal and never a bother but crow in the morning.
Be sure to check out Captain Andy's Na Pali coast tour, we paid extra for the southern star boat. Also for cheap good eats go to Pula Dog in Poipu and Paco's Taco's north of the Marriott.
Lastly the rooms have a mini fridge and no one seems to care if you bring your own food and drink down to the pool or beach. Given its a resort proves for drinks are on the high side so head north to Safeway and pick up a few bottles of your favorite whiskey or rum and spice up your coke.
