I was wondering how you find out if your waitlist comes through? Before the used to call you but the woman I talked to at MS said something regarding "we just switch you and you can see it on the DVC website" .
Is that in the vacation details section where that would show up?
Login to DVC member website. Click "My Vacation Points" then click "View Vacation Details." If your waitlist has come through, you will see it listed there. You also may be able to tell by the number of points available, if filling your waitlist changes the number of points used for your reservation. Good luck!
