So as dvc owners, we can exchange points for some places through rci (although not a good use of points) but have no other rci benefits. Right?
That's correct. You have access to about 600 out of 3,200+ RCI resorts, but none of the other benefits like Extra Vacations and Last Calls.
Generally, with ANY timeshare system whenever you exchange out you are going to either pay a premium or you're going to exchange for a timeshare of lesser quality.
However...that does
not necessarily mean the exchange is not a good use of your points. If you are happy with what you get, that's a good value for your points, and I'll give you an example.
Last October, we did an RCI exchange with Wyndham points to a little place on Cape Cod for a family trip. The place was WAY below Wyndham standards, but we got a 1 BR and a studio for a cousin, the rooms were large and spotless, the staff was friendly and gracious, and the place was <3 miles from our uncle's house. There are certainly better resorts on the Cape, but this was a last-minute trip so we took what we could get. It was a great exchange - for us, for that trip.
I would never purchase DVC with the intent of using DVC points in RCI, nor would I recommend that a prospective DVC buyer
even consider RCI when making their buy/don't buy decision. I probably would never deposit DVC points into RCI unless they were expiring...and there is really no excuse for letting points expire.
But if you are IN DVC, and you want to use your points for an exchange that you are satisfied with, go for it!
