We had such a great time!! Four adults, one tween and one teenager - there was something for all of us. The house itself is spacious, clean and very comfortable. We even liked the beds which is rare for us! The kitchen was well stocked with tools and equipment so were able to make meals - rice cooker, blender, toaster as well as basic ingredients (oils, sugars, salt, pepper). While we did not use them, there were many movies at the house to choose from and the local Foodland market had a Redbox for DVD rentals (about 0.5 mi walk). The closet of beach supplies was overwhelming - dozens of snorkel masks and fins, a few boogie boards, flotation devices, beach chairs, coolers, reusable shopping bags and even little kid/toddler life jackets.
There is a binder of info in the house that gives good tips on where and when to get meals for discount rates. Also tips on which beaches to visit - the beach at the Beach Club is amazing and the snorkeling at the black sand beach (to be nit-picky the beach is more 'mottled' but still super hot to walk on so definitely take shoes with you to that one!!) was really great (be sure to go in the morning). We walked to the beach at the Fairmont, its about 0.5 mi away, it was nice but much more crowded than the other two. And the roads have a wide shoulder and low speed limit that made for nice morning jogs around the Mauna Lani area.
Lastly, there was a drawer of sunscreens left by previous guests which was really nice for use at the pool but do remember to use "Reef Safe" sunscreen at the beach :)
