As we checked into the hotel, our first impression was "Wow, this place is beautiful!" The lobby is tastefully decorated in the local Hawaiian style and somewhat open, yet with covered walkways to protect you from the occasional tropical shower. The staff was very friendly, as they even greeted us personally by using our names. You truly got the feeling that every member of the staff knew you personally and that you were a member of their much-loved family. Walking from the lobby to your room, you pass by tropical gardens with peaceful waterfalls. There is bougainvillea in planters here and there, and I swear we noticed a distinct smell of plumeria throughout the resort. The rooms were more than comfortable, with good views--either Mauka (mountain/land) views or Makai (ocean) views--average-sized bathrooms, and turndown service in the evenings. We were on the Mauka side, and were blessed with good weather every day of our trip.
This hotel is on a pretty good area of Kaanapali Beach, as it is relatively free of rocks. The pool was very large, with a tropical waterfall that you can stand under. If you do not have children and do not wish to be around children, this seemed like a pretty good choice, as we only noticed a few children here and there, and those we saw were very well behaved.
The hotel is somewhat close to the historic Whaler's Village (half a mile away), and during the time I visited, there was a shuttle that offered transportation; however, I honestly cannot remember if they charged for it. There are restaurants on-site, but they are pretty expensive. I would recommend traveling to Whaler's Village, or if you have a car, Lahaina, as you'll find much better prices there.
