I recently stayed for a few days at KoOlina Resort, conveniently close to my family in Ewa Beach. The upside: clean hotel-type room with nice ocean views, kitchenette; no street traffic; great pools & work-out facility, as well as a store & coffee bar. I really appreciated the recycling bins on each floor! A few caveats: expect regular passenger jet noise as this property is in the landing pattern for HNL; plan trips off-campus in advance, geared to the freeway rush-hour situation; and, there is no wheelchair scooter rental concession on-site, so plan for that as a separate pick-up/drop-off in Honolulu. Other than that, great place to stay!
