I came to Kona for a week of scuba diving and it worked out just great for me. The dive shops (Jack’s and Kona Honu) are all close by, and our main sites were about 10 mins away.
Points for divers…
1) there’s no rinse area so be nice and don’t bring in a bunch of black sand…
2) parking is scarce, you will often need to park on the street and if it’s busy you may have a hike
3) try to be on the ground floor if you’re lugging gear
