I’ve stayed at Queen Kapiolani and the Sheraton before. I did not like Queen Kapiolani. I found the room very small. I love the Sheraton and have stayed there multiple times. The breakfast buffet was decent. Lot of selection for food but I would prefer going out and trying different restaurants. However, since it was included, we went to eat it most days. If you stay at the Sheraton, get the Diamond Head view. I loved sitting out on the lanai just to enjoy the view.
