We go exactly when we want to Lagoon because we own there and only go there every year. That being said, Grand Waikikian is a good second best. Rooms are a bit larger in general for what you get but Gand Waikikian has faster elevators, I think one more elevator, larger elevators and a washer / dryer in each room that is convenient. You only need a 1 bedroom ocean view in either Lagoon or Grand Waikikian. Location is better with Lagoon if you like the beach access. Grand Waikikian rooms over all are nicer, though after the upcoming renovations they should be very similar. Problem with the Hokulani is that when you are out your last day you are out at 10 am, while if you have a later date you have the Grand Waikikkian members lounge to store your stuff, enjoy the property for the rest of the day, shower, relax until you leave for your flight later that day. Holulani is not as close to the water city property that looks fine though we have never stayed there.
