The HILTON WAIKOLOA VILLAGE sits on a very large property. In fact there is a train and a boat to take people from one tower to another. If you don't want to wait and choose to walk instead, it can take 15 min to get from the main lobby to either end. The walk to the lagoon beach is also 10min over several stairs/bridges.
Great facilities but it can take some time to get around. Highlight is the lagoon full of fish and turtles.
costs for drinks/snacks/food onsite is also on the pricey side. However, there is a couple of shopping centers 15min walk outside the resort. There is also a shuttle during the day. This opens up more options for food and drinks.
There is also a Walmart in Kona 20min by car to stock up on supplies. Several nearby public beaches.
