I am travelling with my teenage sons to the Big Island. We are based at Waikoloa on the West Side of the Island. We plan to travel to Hilo and Volcano Park. Were going to do a day trip, but are now wondering if we should stay over-night in order to best explore. We are there 7 nights, already booked at our condo, but would do an overnight trip if you think its worth it. Any opinions out there?
