Itinerary advice

Looking for advice on two itineraries on two different days. I'm not sure if I'm trying to do too much each day as the drive seems long-ish for an out and back. That said, are there any don't miss things along the way (we're not big hikers), either day, or in Hilo?

Day 1: leave from Kona Village. Drive to Greenwell Farms for a tour. Drive to Ka Lea then Punalu'u Beach. Return to hotel. Day 2: leave from Kona Village. Drive to Akaka Falls, Rainbow Falls, then explore Hilo. Drive to Kilauea. Return to hotel.
