We had a decent time at Hanalei Bay Resort.
Pros: two pools, kid friendly, on-site dining, close-ish to a small snorkel-friendly beach. Very friendly and helpful wait staff, bell hops and front desk staff. Stunning views and well-kept grounds.
Cons: Some sanitary issues that were eventually fixed by the property management. Not 100% transparency in communication with regard to current state of the unit. Very thin walls, I could hear the conversation of the upstairs neighbors as if they were in the other room. Roosters waking you at 5am. Yes, roosters are all over Kauai, but fewer on other resorts. A unit near the small pool is a unit near the grills and they were VERY smoky. The small pool area also had a dead fish smell that would waft over every few minutes. Not walking distance to any town, must drive.
All in all however, the pros outweigh the cons. Although I don’t think we would stay in the area again due to the location.
