I've been to several resorts in Hawaii. I'm not sure if all of these are available to
DVC or if some of them are below the quality filter. These are in order of recommendation.
HGVC Lagoon Tower, Oahu: We had a 3BR Penthouse on the top floor of the tower. We had the "worst" of the four corners (away from water/Diamondhead) but the views were still breathtaking. I'm not sure these are being deposited anymore, but if you can get one, get it. At one end of the Waikiki strip, so walking distance to a lot of restaurants/night life/activities. You might not even need a car here; we didn't have one. I would stay in this unit again in a heartbeat, but I'm not sure they deposit the penthouses anymore. There are other timeshare towers here, and some of them might also be deposited. If you can't get a penthouse, I might demote this below the Waikoloa resort, because it's more city than island for me.

HGVC Kings Land, HGVC Kohala Suites, Big Island: These are two of the four resorts in Hilton Waikoloa Village. Except for Ocean Tower, none of them are on the water/have water views, but they are all very close. Kings Land units are *very* nice, as is its pool. Kohala is a barely discernable step down but still quite nice. I'm not sure if Ocean Tower can be had via RCI. I've not tried Bay Club yet; the units are reportedly larger, but they do not include pool access at the main hotel complex, while the other three all do. We stayed in 2BRs in both cases. The complex is nothing short of amazing, but the food situation there I thought left a little to be desired.

Kauai Beach Villas, Kauai. Stayed in an oceanfront 2BR via Wyndham points (can guarantee view). Units are dated but comfortable and well equipped. There isn't much development right there, so it is very peaceful, and there is a state park just up the beach; it is walkable if you are willing to climb over a bit of downed driftwood (which might be gone by now) and ford a small trickle of a stream. Local food is limited but a lot within an easy drive. Not sure if I would do this if I wasn't oceanfront, but we liked it so much we bought two 2BR annual oceanfront weeks there (only paid the transfer fees, so next to free). Personally, I'd promote this one if you could guarantee oceanfront above the Waikoloa resorts, but you have to be okay with less plush furnishings. (I am.)

Pono Kai, Kauai. Not sure I'd recommend this one, but I only stayed in the smaller units with a tennis court view. There is just one building of these; all the partial kitchens are there. It was a last-minute thing and I just needed an extra place near KBV for some unexpected guests. The larger units look like they might be nicer and it is in a sheltered area of beach so the swimming is very gentle. More development here, but the plus side is several restaurants are walkable.

Paniolo Greens, Big Island. Up the hill from the Hilton complex, maybe a ten minute drive (if that). Has a little bit of an apartment complex vibe, often fairly easy to get via RCI, because there are a lot of units deposited and it is a little far from the water. Again, another last minute week I was trying to get near the Hilton complex for unexpected guests. It was okay. It would do in a pinch, and we'd do it again if there were a need to be on the Big Island on short notice; lots of good beaches are an easy drive but there are better choices.
