I've never been through Dave's site.
I go to WDW on the average of every 3 months. The last 4 trips and the next in Oct I have rented from the DIS site. (I'm going again to Orlando in 2 weeks but going to visit other parks and just going to DWD for 1 day for my 25th anniversary) Usually the going rate is 10 to 11.00 per point. You can also get references to those renting. I have a standing agreement with 1 person to pre rent 80 points per year @ 9.00 per point. I pay them in advance then tell her when I want it and where avalable. Another I just rent casually. Old Key West has the least of rental points needed for a stay and usually where I want to stay from now on. I stayed at Saratoga. It was alright. The Gym is awesome.
