Just got back today from a week's stay in a 2/6/4 unit - it was fabulous. We did get an already-renovated unit, and it had a really beautiful partial ocean view. It exceeded our expectations, it was really perfect - very spacious, big lanai. I don't know your chances of getting a renovated unit, but everything in ours seemed brand new (except for the stove burners).
We love Kona and this was our 4th trip to Big Island, so that's part of it, too. We like to be waterfront, and we like to be as close as possible to the beginner's snorkeling beach, so we can go there every day without much of a drive. And we did. There were lots of sea turtles there daily, more than we've seen in the past.
