Doc: this prior response from you is what confused me (see underlined portion):
Yes, you could reserve at SSR using Developer Points and then cancel to use them for a World Passport exchange.
"Just be certain that MS is able to "hold" the RCI exchange for you before cancelling the
DVC reservation or it's possible to end up with no reservation. RCI does allow a "Hold" for 24 hours for some resorts and until business close for others -
so you should be OK if you can find availability at a DVC resort thru RCI. There have certainly been some recently - I saw 3 weeks available from late August thru mid September for 1BRs at SSR yesterday and
many others have been able to get other DVC reservations via RCI trades."
It didn't make sense to me that you could use points to "trade in" to RCI and then trade back in to DVC, but I thought (mistakenly) that the above statement seemed to indicate you could.
