The SO-SP conversion for VOIs with high MFs (e.g. WSJ, WPORV, WKORV/N HRA...) are not worth it - unless extreme fuzzy math is applied as done by SVO Sales.
I hear this argument ALL the time on TUGG. However, it doesn't take fuzzy math to say it is NOT WORTH IT -- obviously it depends on where you use the points. Do you ever go to New York, San Francisco, St John Westin, Chicago, Iowa City on a Football weekend, etc....many times these rooms are $400+/night and take 7,000 to 16,000 points. St John can run upwards of $1,000/night and in Europe you can save big money too. I wouldn't say using points at a FourPoints makes sense, but you have to admit those who have these timeshares through Starwood aren't usually staying at the Fourpoints. They are investing in the Starwood Brand and higher end properties. I have found that 75% of the time we are saving 50% on rooms when breaking down valuations of points we use. In addition to the close to 750,000 points we got through two purchases, using the AMEX on the purchases - we got some nice perks for the intial investment.
As for 40% discount comment - versus retail. I realize you can buy all you want and go where you want or buy at Mandatory resorts - however we are a family that likes to use our ownership and have flexibility to see the world in a high class way that we could not otherwise afford.
Also - I am referring to Bay Vista MF's -- Virgin Grand have ALWAYS been high and I believe it was a lack of funding for replacement that caused much of this. I believe that the newer SVO's are better run in terms of funding for updates and improvements and many costs have been associated with taxes, utilities, labor and insurance costs...just as many of our OWN PERSONAL HOMEOWNERSHIP COSTS have risen ahead of inflation - not to mention healthcare.
We purchased 2 properties through Starwood Direct and 2 properties on the secondary market - were able to do upgrades and retros to get us to 715,000 Staroptions. We got very lucky with the recent re-valuation of St John and the lowest cost MF's per value received ownership in Bay Vista.
This can all change - but we have a good base to build off of and have many benefits to reap before it becomes more painful.
