Great place to get away from everything. Plenty of room to spread out for 3 people in our group. Make sure if you need groceries to stock up before getting to Volcano, very limited supplies and expensive there.
Ben's place is perfect when visiting Volcanoes National Park. While there, I also recommend driving to the lava flow area off Highway 130 (the park has info about it) and renting a bike to make the 4 mile hike in and out. We rented from Jeff's Bikes, one of the first stands past the parking area, for $15 each and they provided helmets, water, headlamps, basket and bungees for bikes if needed. After riding on your bike as far as you can go, you will have about an hour hike over the hardened lava flow to see active lava. Very worth the hike and truly unique!
When you return, there is just a 5 minute walk to see the lava flow into the ocean. The gates to get in open at 3 and I would plan enough time to have some twilight at least to hike back from the active lava areas. The ocean flow is best seen in darkness.
