WSJ is a mandatory property so a buyer will be able to use the StarOptions elsewhere. They won't be able to convert them to Starpoints unless they later requalify the week back into the SVN program. The new section of WSJ is said to be volutnary (non-mandatory). In that case a buyer of a resale unit won't be able to use the StarOptions elsewhere unless they requalify the unit back into the network.
One thing I've learned here on TUG is that if you buy several resales, even at mandatory resorts, you can't combine them to go to a more expensive location. For example, you couldn't combine these 81,000 SOs with another 67100 SOs from another non-qualified resale to get a two bedroom lock-off in Maui for 148,100 SOs. You'd have to make two separate eschanges for a 1BR and 1 studio and they may not end up being connected once you get to Maui. You also couldn't combine SOs to exchange into a 3 BR at WSJ, even if it were available.
