I am planning a 14 day trip to the Big Island at Christmas time 2017. I have stayed near HVNP and in Kona on two previous trips. I am planning to spend 3-4 nights near HVNP, and the rest of the time near Kohala for a change of scenery and because I haven't spent any time in that area. I prefer to rent houses, and I am looking at a house in Kamuela at 1,500 above sea level. Is that too high up? Will it get too cold at night? Below 65 degrees will be too cold for me.
