I don't think you can rent that few of points through David's. If you can, do it. If not, I wouldn't pay much more. We did a cash rez for 1 night before we owned DVC and for the price we paid, I can't say it was worth it. The pools were cold and we just weren't there long enough to take advantage of what they had to offer. The kids splash area, river, and slides closed at 5 or 6 pm, shortly after we checked in. That being said, we're going back in december, but on our points, and for longer so we can experience more.
