Has anyone stayed at the Hyatt on Waikiki Beach?

I am going to Oahu after going to Maui and Kauai. I am spending my last few days in Oahu. We are expecting to spend more time outside and ';having fun'; on out last few days of our honeymoon. We are spending alot of money on hotels in Maui and Kauai, so I am looking for something a little less expensive, but not cheap. I am staying at the Four Seasons in Maui and Hyatt in Kauai, so this hotel will just be for the last few days of the trip. The Hyatt on Oahu looks ok and at an ok price. I am trying to save somemoney on this portion after the extremely expensive hotels in Maui and Kauai. Any help would be greatly appreciated. Thanks.
