Checked out of a 1BR 3 days ago
We just checked out of Kona Coast II 3 days ago. We had a 1BR unit (top floor) and were quite pleased with it. It was one of the 2 largest timeshare units we have ever stayed in, and the decor, fittings, and construction were just a notch below what you would find at a Marriott or Starwood timeshare. And we enjoyed the location. Don't expect a big pool...or fast internet. Buildings 19-27 have the best views, except for building 20. If we were to do it again, we would ask for building 26, as it appears that you can enter there on the 2nd floor and not have to lug your bags up 2 flights of stairs (there are no elevators). No one pressed us a bit to attend a timeshare presentation, though we learned we could receive $79 (I think it was) for attending if we wished to.
You should be aware that there is an extra charge for electricity if you elect to have air-conditioning (we found it useful). The current rate for a 1BR unit is $8.xx per day, a bit less than for a 2BR unit.
For inexpensive dining, we highly recommend Da Poke Shack (if poke is your thing) and The Thai Restaurant in the mall just above the resort. Peaberry & Galette is also nice, but not cheap, for breakfast...if you like an assortment of tasty crepes. Be sure to get your Aloha Privileges card when checking in. It will get you a 10% discount at The Thai Restaurant...and some others.
Bring your Costco & Safeway cards if you have them.
For snorkeling, start with Kahalu'u Beach, then try City of Refuge...or Mauna Kea beach if you like sandy beaches. For last 2, be sure to arrive early (before 9 am) if you want parking. It's best to avoid weekends here.
For City of Refuge ("Two-Step"), you may arrive later if you don't mind paying the National Park fees for entering and using their parking lot. But we showed our National Park Golden (senior) Pass along with a military ID card and were not charged a cent.
