We stayed for a week with our 2.5 year old and this was the perfect place for our family! The condo has everything you need. A big balcony, great ocean views from both the living and bedroom. We loved the location of both the hotel and the condo (almost top floor, corner unit). We hope to come back soon!
You do not need a rental car to stay here but if you do want to explore Oahu for a few days, we parked our rental car at the Ala Wai harbor which is just next to the Hilton (10 minute walk) for $1 an hour instead of valeting at the hotel for $35 a day.
