Brandon’s unit (Hale Kona #10802) is a great place for two persons, you can squeeze in another adult because there is a sofa bed available but fourth adult would be too crowded. I think it is best for a couple because of its size. The next door unit is double the size of it and we could hear the occupants because of the door between the two rooms. With small kitchen we could managed to prepare something to eat and drink but the utensils are limited for two persons. There are microwave, coffeemaker, electric kettle, bread toaster, and rice cooker. The king size bed is firm and pillows are comfy. There is a small balcony facing the two harbors and those petroleum tanks. The resort is beautiful and the ground is well maintained, thanks to many Filipino staff working there. You can walk and swim to all four lagoons. Ko Olina is far from busy and crowded Honolulu/Waikiki so make sure you have a rental car to see more places, parking is included with Brandon’s unit. Side note, Marriott’s unit numbering is confusing, unit 10802 is at the 8th floor. Washer/Dryer are at 4th and 10th floor only.
