We start our BI trip in VNP for 3 days. Then to Kapoho for 4 days. I would like to spend our last 2 nights in Kona. Especially being an Ironman fan. Thinking about touring a coffee plantation and a manta ray dive. We are 2 couples and are looking for a condo. Our budget is $250/night and would like to walk into town if possible. But not a priority. Is there anything beachfront that works for us?
