The person who inputs the new memberships does it chronologically based on when your contract closed and the info was sent to Disney. For most people, it's been taking about a week to get into the system and another few days for your points to be loaded.
I closed (resale) late March and it took two weeks to get in the DVC system.
I too was anxious...I called MS a few times during the two weeks and it made no difference in expediting the timeframe. MS was very nice when I called but they have to do things chronologically.
We closed on a Thursday, in the Orange County records on Friday and membership in the following Thursday. I called Thursday to find out where all my points had gone and they said it can take up to a month for the points to show up. They were there the next day.
On a side note, anyone know why they would put your membership / contract info in and not the points until later?
