I am going to give Wind in the Pines a whirl this winter, so we'll see.
Oak n Spruce is fine and units are definitely nicer/newer than WITP, mileage varies at OnS depending on where you end up. Prepare for stairs, loud neighbors and painfully slow checkin with pushy sales pitch. Very crowded pool in summer if you care about that. Location is great, which is the only reason I stay there. I've not had towel issues but we usually have fewer people than the unit occupies so it works out ok.
