We just had 3 nights here as part of a Hawaiian islands holiday.
Chose this as we are spg members and location on Waikiki beach.
Everything about the hotel was great except the room, we were in 264.
Noise from the room next door was at times intrusive but did not keep us awake.
Room was big but the beds were standard size, not great when travelling with 2 kids who don't like sharing.
Bathroom absolutely tiny, good standard of fixtures and very clean but really small. While appreciate that it's an old hotel it wouldn't be difficult to improve on these things.
Room needed more lighting too, these energy saving lights are not as bright so at least one more needed.
Possible we'd stay there again but would look elsewhere first.
