You have to pay attention to the unit you get at the Pono Kai. There are a few management companies there managing units. For the Pono Kai owners association, all the units won't be done until into 2018. Even with the renovations i wouldn't say they are Marriott quality. i did upload some of those pictures here on TUG. They are definitely nice and a big improvement. I'll be there in 48 days but who's counting.
if you rent, there are also many whole owned units in varying degrees of being upgraded so you have to be carefull. That is why the reviews vary greatly on the Pono Kai.
I don't know if the unit we're in is renovated or not but we'll get one for sure in 2018. We find staying in Kapaa convenient at anytime of the year.
