I've stayed at a few resorts and hotels in the Waikiki area, and I would definitely recommend Wyndham resort through Shelby. Next time I'm in the area, I would be staying there as well.
Rooms were clean and well-maintained. If we needed more supplies like towels, soap, or kitchen tools, the staff responded within minutes. They were very attentive and friendly, but not to the point where it's uncomfortable.
We loved the location of the resort too. It's super close to the beach, transportation, and restaurants, and there are lots of shops right outside the resort to look around, but the neighbourhood is still quite enough at night to get a good sleep.
