It's a cheaper stay if you own Wyndham and trade into SSR than it is to own SSR and pay dues on it. If you own within multiple systems, it allows you to alternate between Wyndham points and DVC points while still getting a DVC vacation every time as long as you are okay with frequently staying at SSR. It cost me $1000, including purchase price dues and fees, to trade into a week at SSR. A lot of people on TUG that are Wyndham owners are also DVC owners. I was planning on getting a small DVC contract to use about1/4th of the time I go to Orlando (I want to go 3-4 times a year to see my family). I want to own Wyndham, WorldMark and DVC. DVC is at the bottom of my list though because the other two are much more flexible where you can go.
I want to trade into SSR using Wyndham, Marriott using Worldmark, and use my points for Bonnet Creek, Reunion, and the new Orlando Margaritaville Vacation Club that is only partially built. There's so many awesome resorts in Orlando beyond DVC. That's an example where it will affect me if I do buy a 160pt DVC contract because that's the most expensive purchase. My Wyndham ownerships will cost me under $5000, the DVC one however will be about $16,000.
The RCI inventory is meant for RCI members and their family, not the highest bidder. If these companies were dealt with properly, more people might realize how great of a deal it is to pick up a resale Wyndham ownership for a few hundred dollars with a good chance at getting a DVC week rather than adding on DVC points for thousands of dollars. If you were to ask the majority of people looking to add on if they were okay with SSR every other time if it meant not having a high purchase price, most people would prefer that option because Club Wyndham does have some badass family resorts on the beach, in the Smokies and at the Dells.
