My update included the following points.
St John is the only Westin property not in Westin Flex.(Not sure if this is true.) It is being added in the next few months.(Also, time will tell) Any St John properties that come back to Marriott via upgrade or otherwise, especially on the hill, are being squirreled away for Marriott exchange.
Marriott will restrict resale owners from using the entire Marriott network. Will not effect mandatory owners from continuing to exchange within Vistana. No mention if they are offering a buy in package for resale owners.
Trying to sell Sunset. Claiming only two seasons. Offer was 2 BR, $62,300 for winter season, $52,500 for summer season. Offer was to trade in my 81,000 Orlando unit and requal my WSJ VGV final prices were $32,760 for winter & $26,600 for summer. Then they offered a 148,000 Bay Vista 2 BR float wk 19 - 34 for $19,095, trading in my 81,000 Orlando unit and requal my WSJ VGV. (When i upgraded my inherited 67,000 Orlando to 81,000 it was $10,000 in 2007.) Prices were supposedly a discount price for current WSJ owners.
