We had a great time at Honua Kai resort. Our suit (533) had great view of the ocean and our daughter really enjoyed the pool and the slide. Duke restaurant was just next to the pool- super convenient to get quick lunch and drinks. We would definitely come back again. However we suggest you to enter the ocean in front of the Westin which is 5- 10 minutes walk from Honua Kai since there are more rocks in the ocean in front of the resort.
P.S. we requested a complimentary late checkout from Maui Resorts Rental and they were very responsive and accommodating.
