Staying at Tony's Milolii Whale House was a real treat! We didn't have a lot of sunny days while we were there, so didn't have the chance to use the pool as often as we would have liked, but the one day we did, it was wonderful! Even if it wasn't pool weather, there was nothing to complain about. Sitting on the lanai, watching the ocean, and listening to the birds and the rustle of the palms was so relaxing and let me know I was in paradise. It's further from the ocean than it looks in the photos. I missed the sound of the ocean, but the view is incredible and made up for it.
The Whale House is quite a distance from any stores, so I'd recommend visitors be prepared to shop for at least their first day or two. The house has a pretty good selection of spices and condiments, probably left by other guests. I know we left mayo, mustard, bbq sauce, butter, and maybe even a beer or two. But, ya never know what will be there, or not. Sugar was a "not" for us, but we made do without it. During excursions out to see the Island, there are plenty of stores for picking up things as needed. We actually stopped at a store in Ocean View and got some eggs and ribs at a better price than we would have paid at Walmart - if they'd have had any in stock.
The only other thing I'd recommend is to try to get to the house before dark. The road from the main highway is about 4 miles long and filled with twists, turns, and blind spots. It's also quite steep in places. It's not a bad road, just not one to be driven on for the first time in the dark. Not to mention, it would be hard to see the fruit or avocado stands in the dark!
