We had the misfortune of being on the Big Island during an abnormal weather pattern, but the condo was an oasis in the storm. Huge lanai, kids sand toys, beach chairs, and some inflatable tubes were there. The turtle beach next door never failed to disappoint. The owners, Dennis and Sherron, were a pleasure to deal with and attentive to any questions we had, more so than any other condo owners that we have dealt with in the past. If they didn't know the answers to our questions, they found out. Great condo reference book on site. The unit is right on the water, so expect some minor issues attendant to the location (everything needs to go in the fridge, otherwise the ants will come out; one time a gecko got in).
We recommend the Sea Horse farm, Snorkeling with Manta Rays on Hawaiian Oceanic, and the Dolphin Experience for kids. As far as food, Da Poke Shack is walking distance, although we preferred Umeke's in town. There is no barbecue at the condo, so plan accordingly.
