Can't speak for Honolulu, but the Shell Vacations Club Holua Resort at the Mauna Loa Village or Shell Vacations Club Kona Coast Resort, are fantastic uses of 15k a night Wyndham points. Both are on golf courses near one another and right on the water. neither have beach access as that side of the Island is more rocky. But, you're within a 10 minute drive from some of the most remarkable snorkeling spots.
