Sorry if I'm straying off-topic here, but I don't know, I find the whole rental process intimidating. Like I said, I've never done it before, so maybe I have it over-blown in my head, but the whole process of listing your points, agreeing with a renter (do people negotiate price?), making the reservation, making any changes to the reserveration, collecting your money, keeping track of the profits for tax purposes, etc., seems pretty time consuming. You also run the risk of getting scammed along the way, which I know is very rare, but with my luck would happen to me.

Multiply this by the number of rentals you would have to do to get enough cash to pay for a cruise. Not for me, not at this point anyway. Although..... it DOES sound pretty lucrative, even if I only make 3.00 or so profit per point, the amount saved can sure buy a lot of Konk Koolers!

Right now, with 3 kids and a very demanding job, time is my most precious resource. I look to DVC to provide rest and relaxation, not cause more work for me. I'm just not sure if in my particular situation, renting is worth the hassle. I'd rather just pick up the phone and be done, and use my energy to plan my excursions. Maybe if my situation changes, I will start using the renting/cash strategy. But for now, I'm just happy that Disney offers the option of cruising on points.
Oh, and I always buy
travel insurance for a cruise to mitigate the risk... add that to the cost. But I guess travel insurance is a whole other debate.
