Hands down the Sheraton Waikiki! Fh and I love Hawaii. Our favorite in Oahu is the royal hawaiian, which is right next to the Sheraton. Both properties are owned by starwood and if you stay at the royal Hawaiian you can also go over to the Sheraton and use their amenities (unfortunately it's not vice versa). But we went to the Sheraton a few times and had a great time. The pool is amazing and the have a great bar for happy hour right on the water. I can't say enough good things. I've eaten at the mar riot and looked around and it didn't even come close. I don't know much about the hyatt.
Have you looked into the Moana Surfrider? It's an absolutely gorgeous property!
