we are a family of 5 and will travel to Big Island on Dec 15-26 this year.
Staying in Waikoloa Village seems like good option.
Looking at the forum posts it should be sunny there and beaches are near to reach by car.
I found in web a nice looking apartment at reasonable price to stay.
However it does not have air condition.
What is average day/night temperature in Waikoloa in December, will it be too hot inside without A/C?
Thanks for advises.
