8.6/10 Excellent! (2,109 reviews)

Had a nice stay . Breakfast was great and so was staff. The only bad thing was I book a room with 2 beds and they didn’t have it available when we went to check in. But they did up grade the room that had a balcony and ocean view. Which was beautiful and relaxing. The pull out sofa was terrible. But over all it was beautiful in Hawaii !!!

The Waikīkī tower at the Ala Moana Hotel is undergoing renovation. This Luana Vacation rental has recently been refreshed. Bright colors and updated furniture really have improved this property. Good value for the money
