We were recently in Hawaii. We choose to stay on Wikiki. We looked at Aulani. We found it was way more expensive than similar hotels. A rental car is needed as none of the tours do pick up's from Aulani. You will not find a similar pool area at a Wikiki hotel. However, we spend zero time at the pool, we spent it at the beach.
We didn't rent a car. We could walk to many places. We used the trolley. We also booked a couple tours to take us around the island. They pick you up right at your hotel and there are hundreds to choose from.
