We've been to Maui many times, but this was the first visit with our daughter. The Sands of Kahana and Unit 318 in particular were PERFECT for a family with a toddler: easy access to the pools/beach, restaurant on site, kiddie pool with hot tub, relatively calm ocean waters, and a shower w/ tub. We would absolutely stay here again.
Other pros: gorgeous view, easy parking, great beach, plenty of towels, spacious accommodations. Kelly and her colleagues were beyond helpful/responsive leading up to our stay and during it.
A good review is an honest review, so I would like to note some areas for improvement: we found the bed to be very uncomfortable, the unit is loud due to foot traffic to/from the elevator, they encouraged us to keep the kitchen clean to avoid ants, but didn't provide any cleaning supplies (I found it odd that guests would be responsible for buying cleaning supplies).
Overall, we thoroughly enjoyed our stay and would recommend it to others.
