We are three, aged 74, 63 and 62 and in pretty reasonable physical condition; the eldest wears a pacemaker and really needs to avoid walks of a long duration (over 2 hours) or that involve any kind of steep ascents.
10/22 - Kona Airport arrival at 3:30 pick up pre-arranged rental car, drive to Keahou Kona Surf, check out Kahaluu Beach, dinner at Huggo's
10/23 - Easy Wind snorkel/BBQ cruise, Place of Refuge, South Point
10/24 - Visit coffee plantation (I've been buying coffee from Hua Hua Farms for years, and have been invited to come for a tour), check out several beaches in Kohala
10/25 - Hamakua Coast
10/27 - VNP, with either staying the night there, or returning to Hilo. My thinking is to stay in Volcano, and on the next day, prior to returning to Kona, exploring Puna, black sand beach etc. Does that make sense?
10/28 - see above
10/29 - all beach day?
10/30 - return to reality in Southern Calif
