For units in Waikola area, I like Bay Club first mainly for the size and if I am getting a 2 BR unit. All 2 BRs have golf course views. 1 BRs I likely would go to one of the other resorts.
For outside area and pools and HWV access, I like Kings Land. However the last time I was at Kings Land we only went to HWV pools once. We are usually out scuba diving or doing other things. Not really an issue. I don't go to Hawaii to sit by the pool myself.
Kohola Suites is my least favorite. I have looked at the rooms, but prefer the other resorts.
