This year I tried to upgrade using suite upgrade awards in 3 different months and it is impossible. I tried also through my concierge and allowing flexible dates. It seems this property doesn’t open up rooms for upgrades...
Then decided to try the Waikiki Centric and it worked in all 3 dates. In two stays got the “oceanview” suite (which has the bathtub).
Has anyone been successful using the upgrades at the HR Waikiki? Which suite do they give?
