The location of this unit is outstanding and you’ll love the views of the beach and the mountains from the balcony! The building (we were in #2) is right next to Whaler’s Village which offers great shopping and dining options. You can also sign up for dolphin watching tours, parasailing, snorkeling and other adventures right along Kaanapali Beach. If you are renting a car I would recommend trips north to the Kapalua Tidepools, Honolua Bay and the Nakalele Blowhole and south to Lahaina Town and Makena Beach. Haleakala is also a must do but we prefer sunset over having to get up so early to try and see the sunrise.
My only complaint about the unit was the sofa bed. It was not comfortable at all. I asked for another option and was provided a rollaway (twin mattress) which did the job since we only had two people on the trip. With the rollaway I would say expect to only sleep 3 people comfortably though.
Wish you the best on your trip! Maui is incredible.
