Had a great time with my wife, kids (2y.o. and 4y.o.) and parents, for a 10-day stay over Christmas and New Year's. The access to the Hilton Waikoloa resort pool and amenities was a great bonus - that made for a great day with kids. Centrally located between all the destinations on the Big Island, and we did a lot of driving around and sightseeting, from Volcano National Park to South Point to Pololu valley.
